Abstract:
This article reviews methods for the determination and identification of trace elements in wine by using atomic absorption spectrometry (AAS). Wine is one of the most widely consumed beverages and strict analytical control of trace elements content is required during the whole process of wine production from grape to the final product. Levels of trace elements in wine are important from both points of view: organoleptic – Fe, Cu, Mn and Zn concentrations are directly related to the destabilization and oxidative evolution of wines, and toxicological – toxic elements content should be under the allowable limit, wine identification. The identification of metals in wine is subject of increasing interest since complexation may reduce their toxicity and bioavailability. AAS is one of widely used methods for routine analytical control of wine quality recommended by the International Organization of Vine and Wine. Two main approaches – preliminary sample digestion and direct instrumental measurement combined with AAS for trace element determination in wines are reviewed and discussed. Procedures for various sample pretreatments, for trace element separation and preconcentration are presented. Advances in metal identification studies in wines based on AAS are presented.

Abstract:
Atomic spectrometry and electrochemistry are usually recognized as independent analytical tools used for different purposes. Here, a brief review is given of the advantages of using electrochemistry in the various fields of atomic spectrometry techniques. In the first part, the application of electrochemical preconcentration before the atomic spectrometry will be addressed and exemplified. Electrochemical preconcentration could be used with flame atomic absorption spectrometry (AAS) or graphite furnace AAS as well as with atomic emission plasma sources. The second area of the applications of electrochemistry will be directly focused on the graphite furnace AAS where the electrodeposition onto the graphite surface of the atomizer could be used for both in situ analyte preconcentration or modification of the surface by noble metals.

Abstract:
The importance of arsenic (As) quantification in environmental compartments is due to its risks to ecosystems and public health. There are reports of high concentrations of this metalloid in Brazil and technological differences between states are observed. The objective of this work was to present and discuss current scenarios of accreditation and compare the limit of quantification (LOQ) of As by analytical technique in Brazil. Data from accredited laboratories were collected on Inmetro website and in state metrological networks and then grouped and analyzed by state, matrix and analytical technique. There are large discrepancies between the number of laboratories per state and a good correlation with gross domestic product (GDP). Almost all laboratories have a LOQ less than the environmental limits. The observed list of techniques sorted from lowest to highest LOQ values is: for liquid samples ICP MS (inductively coupled plasma mass spectrometry), ET AAS (electrothermal atomic absorption spectrometry), HG AAS (hydride generation combined with atomic absorption spectrometry) or HG ICP OES (hydride generation combined with inductively coupled plasma optical emission spectrometry) and UV VIS (visible ultraviolet spectroscopy); for solids samples HG ICP OES, ICP MS, HG AAS, ET AAS and FAAS (flame atomic absorption spectrometry); and for bioindicators ICP MS, HG ICP OES. Analysis of As species is accredited in only one laboratory, but does not include all species.

Abstract:
An innovative method of MIP-AAS has been developed. The sample solution was introduced by using an ultrasonic nebulizer. The desolvation was accomplished by a heating tube and a combination of a water-cooled condenser and a concentrated sulfuric acid desiccator. Both an L-shaped and a T-shaped plasma discharge tube were used as the absorption cell in the experiment. The experimental parameters were carefully examined and optimized for the elements studied. Some comparison of properties for these two different absorption tubes was made, and the analytical performance of MIP-AAS was evaluated. The characteristic concentrations obtained in this work were shown to be around ppb under the optimized experimental conditions for 12 elements. Good repeatability and accuracy were achieved. The analytical figures of merit were found to be much better than those obtained by ICP-AAS and previous MIP-AAS experiments and comparable to or even better than the best reported values of flame AAS.

Abstract:
Sportfish samples (n = 133) that originated from Indiana waters were analyzed for total mercury using inductively coupled plasma/mass spectrometry (ICP/MS) and thermal decomposition, amalgamation/atomic absorption spectrophotometry (TDA/AAS). Total mercury concentrations obtained by the two methods were not significantly different (P > 0.05). The correlation coefficient for total mercury obtained for the two methods was 0.94. The limit of detection using TDA/AAS was 0.1 ppm. TDA/AAS is a preferred technique for the analysis of total mercury in fish tissue because it is rapid (6 min per sample) and easy to use and requires little sample preparation.

Abstract:
Abstract The preparations of digested samples of certifiable color additives by dry ashing and wet digestion for arsenic analysis by hydride generation atomic absorption spectrometry (AAS) were compared. The dry ashing technique was based on the preparation used in ASTM D4606-86 for determination of As and Se in coal. The acid digestion method used nitric and sulfuric acids heated by microwaves in sealed vessels. The digested color additives were analyzed for As by using hydride generated from sodium borohydride mixed with the acidified solution on a flow injection system leading to an atomic absorption spectrometer. Dry ashing was preferable to wet digestion because wet digestion yielded poor recoveries of added As. Dry ashing followed by hydride generation AAS gave determination limits of 0.5 ppm As in the color additives. At a specification level of 3 ppm As, the precision of the method using dry ashing was ± 0.4 ppm (95% confidence interval).

Abstract:
Flow Injection (FI) techniques for use with Atomic Absorption Spectrometry (AAS) have attracted considerable research interest for sample introduction and calibration strategies. The interest continues in on-line preconcentration and matrix modification which are carried out by the incorporation of liquid-liquid extraction, ion-exchange, immobilised reagents, gas/vapour generation and continuous precipitation-filtration devices into suitably designed manifolds. Indirect determination of inorganic anions and organic compounds is becoming routine by FI–flame AAS. The direct analysis of solid samples, which is a shortcoming of flame AAS, was recently carried out by on-line electrolytic dissolutions.

Abstract:
A novel analytical technique was developed where gaseous hydrogen selenide formed by sodium tetrahydroborate reduction is transported to and trapped on a resistively heated gold-coated W-coil atom trap for in situ preconcentration. The atom trap is held at 165 º
C during the collection stage and is heated up to 675 º
C for revolatilization
analyte species formed are transported to an externally heated quartz T-tube where the atomization takes place and the transient signal is obtained. For gold, a high volume gas liquid separator (HVGLS) was designed to improve the detection limit of Au down to the ng mL-1 levels. In this apparatus, analyte and reductant solutions are collected in a limited volume and volatile analyte species are formed. After separation of the volatile analyte species from liquid phase, the entire analyte vapor is sent to an atomizer. A W-coil trap was used to further decrease the detection limit. The enhancement factor for the characteristic concentration was found to be 10.7 when compared to HG-AAS performance without W-coil trap by using peak height values. Furthermore, the generation of analytically useful volatile form of Au has been studied. The flow injection generation was performed in a dedicated generator consisting of a special mixing apparatus and gas-liquid separator design. The on-line atomization in the quartz tube multiatomizer for atomic absorption (AAS) detection has been employed as the convenient atomization/detection mean. 198Au, 199Au radioactive indicator of high specific activity together with AAS measurements was used to track quantitatively the transfer of analyte in the course of generation and transport to the atomizer. In-situ trapping in GF for AAS was explored as an alternative to the on-line atomization. Transmission electron microscopy measurements proved the presence of Au nanoparticles of diameter of approximately 10 nm and smaller transported from the generator by the flow of carrier Ar. For silver, three types of GLS which are U-shaped, cylindrical and high volume gas liquid separators (HVGLS) were used to compare the sensitivities of these GLSs during Ag determination. The DL (3s) values were found as 29 ng mL-1, 0.4 ng mL-1 and 0.05 ng mL-1 for U-shaped GLS, cylindrical GLS with W-coil trap and HVGLS with W-coil trap, respectively. For indium, two types of GLS which are cylindrical and HVGLS with W-coil trap were used. The LOD and characteristic concentration were found as 148 and 317 ng mL-1 with cylindrical shape GLS. HVGLS with W-coil trap was used to improve sensitivity. In this case, LOD and characteristic concentration were found to be 0.46 and 0.98 ng mL-1, respectively. Moreover, to increase the reactivity between indium and reductant solutions, Ru(acac)3 catalyst was used. In this case, LOD and characteristic concentration were found to be 0.13 and 0.23 ng mL-1, respectively. In the case of using this catalyst, sensitivity was enhanced around 1378 fold with respect to cylindrical GLS.

Abstract:
Nowadays, magnesium alloys are used in many sectors of human activity, particularly in the aerospace and automotive industries, due to a combination of good mechanical properties and low density of magnesium. Recently, however, the attention is paid to the possibility of using magnesium alloys in the medical field, mainly due to the chemical properties of magnesium. The diploma thesis is focused on evaluating of the corrosion behavior of AZ31alloy and AZ61 alloys in SBF solutions that are solutions simulating body fluids. The alloys were subjected to immersion test in Hank’s solutions for time span from 24 to 1008 hours. The corrosion process was evaluated based on several factors: alloy composition, time and pH changes. The thesis also describes in detail the methodology for establishing magnesium and zinc by method of flame absorption spektrometry (F AAS). The determination of aluminum was carried out by atomic absorption spectrometry with electrothermal atomization (ET AAS).

Abstract:
The diploma thesis is dealing with monitoring of arsenic in foodstuffs. The aim of this thesis is the determination of arsenic in samples of fish and rice and the study of forms, in which arsenic occurs, using speciation analysis. Arsenic is known as a toxic element, but its measure of toxicity depends on the chemical form it occurs in. Arsenic is present in the environment naturally or it gets in the environment by human activities. Complete characterization of arsenic compounds is necessary to understand intake, accumulation, transport, detoxification and activation of this element in the natural environment and living systems. The field of arsenic speciation analysis has grown rapidly in recent years, because determination of the total element content is not sufficient in the case of arsenic. Speciation method was done using separation by high performance liquid chromatography and detection by atomic fluorescence spectrometry with hydride generation. Extractable arsenic was present in the form of nontoxic arsenobetaine in all analysed samples of fish. In samples of rice there was confirmed the presence of toxic inorganic species of arsenic, esspecially As (III), but their concentration was at low level.

In the last decade, the extraction magnetic solid phase (MSPE) has been intense study target in Analytical Chemistry, mainly because of its potential application in sample preparation. Recently, with the development motivation automatic analytical methods, this technique has been combined with flow systems. However, the synergistic integration of MSPE with these systems is still a challenge, especially when it involves the handling of viscous matrices. In this perspective, this thesis proposes the development of an effective automated method to perform the MSPE in aqueous and oily matrices. For be applied as magnetic adsorbent nanoparticles of Fe3O4 coated with alumina and functionalized with sodium dodecyl sulfate (SDS) and 1-(2-pyridylazo)-2-naphthol (PAN) were synthesized. The nanoparticles were characterized by diffraction analysis X-ray and scanning electron microscopy, where it was confirmed that the method used to obtain the particles was adequate. Secondly, the automatic system to run the MSPE was developed. To this end an extraction chamber was made of Teflon with a quartz window on the side, where all steps of MSPE was performed without the need for any auxiliary apparatus for immobilizing the adsorbent. For generating the magnetic field in the extraction chamber, a robotic device has been developed. After these steps, the applicability of the method was demonstrated in the extraction and preconcentration of Cd and Pb in drinking water samples and Cd in edible oils, using as detection atomic absorption spectrometry graphite furnace. Factors affecting MSPE, such as pH, the amount of adsorbent, the type and concentration of the eluent and the elution time were studied. In the best experimental conditions to the sample water, the detection limit was 0.004, and 0.043 ug L-1 for Cd and Pb, respectively. Even in this array, relative standard deviations less than 3.5% were achieved with a 15-fold enrichment factor for both analytes. In the case of determination of Cd in edible oils, detection limit (0.006 ug L-1) and standard deviation (< 3.3%) was obtained satisfactorily with a 9-fold enrichment factor. Interfering studies have been performed successfully for the two determinations, not revealing significant percentage interference in determinations. The developed automatic method is simple and robust since it does not require immobilization of the adsorbent, and was successfully applied in the determination of Cd and Pb in drinking water samples and Cd in edible oils.
Na última década, a extração em fase sólida magnética (MSPE) tem sido alvo de intenso estudo na Química Analítica, principalmente em virtude do seu potencial de aplicação no preparo de amostras. Recentemente, tendo como motivação o desenvolvimento de métodos analíticos automáticos, essa técnica vem sendo combinada aos sistemas em fluxo. Contudo, a integração sinérgica da MSPE com esses sistemas ainda é um desafio, principalmente quando envolve a manipulação de matrizes viscosas. Nessa perspectiva, a presente tese propõe o desenvolvimento de um eficiente método automático para realização da MSPE em matrizes aquosas e oleosas. Para serem aplicadas como adsorvente magnético foram sintetizadas nanopartículas de Fe3O4 revestidas com alumina e funcionalizadas com dodecil sulfato de sódio (SDS) e 1-(2-piridilazo)-2-naftol (PAN). As nanopartículas foram caracterizadas através da análise de difratometria de raios-X e da microscopia eletrônica de varredura, onde confirmou-se que o método empregado para obtenção das partículas foi adequado. Num segundo momento, o sistema automático para executar a MSPE foi desenvolvido. Para isso, uma câmara de extração foi confeccionada em Teflon, com uma janela de quartzo na lateral, onde todos os passos da MSPE foram realizados sem a necessidade de qualquer aparato auxiliar para imobilizar o adsorvente. Para geração do campo magnético, na câmara de extração, um dispositivo robótico foi desenvolvido. Depois de estabelecida essas etapas, a aplicabilidade do método foi demonstrada na extração e preconcentração de Cd e Pb em amostras de água de abastecimento e de Cd em óleos comestíveis, empregando como detecção a espectrometria de absorção atômica em forno de grafite. Fatores que afetam a MSPE, tais como o pH, a quantidade de adsorvente, o tipo e a concentração do eluente e o tempo de eluição foram estudados. Nas melhores condições experimentais, para a amostra água, o limite de detecção foi 0,004 e 0,043 μg L-1 para o Cd e o Pb, respectivamente. Ainda nessa matriz, desvios padrão relativos menores que 3,5 % foram alcançados com um fator de enriquecimento de 15 vezes para ambos os analitos. No caso da determinação de Cd em óleos comestíveis, limite de detecção (0,006 μg L-1) e desvio padrão relativo (< 3,3 %) satisfatório foi obtido com um fator de enriquecimento de 9 vezes. Os estudos de interferentes foram realizados com êxito para as duas determinações, não revelando interferência percentual significativa nas determinações. O método automático desenvolvido é simples e robusto, uma vez que não requer a imobilização do adsorvente, e foi aplicado com sucesso na determinação de Cd e Pb em amostras de água de abastecimento e de Cd em óleos comestíveis.

Abstract:
High temperature corrosion and fuel system fouling are major concerns that confront gas turbine users. Fuel treatment is a critical requirement for gas turbine operators burning alternative fuels and even so called “clean fuels”. Spectrometric fuel analysis is used to determine the amount of treatment required as well as the efficiency of the treatment. In most cases, analytical techniques developed by chemists for use in laboratory environments have been adopted for field use. This paper describes the various spectrometric techniques available to the gas turbine user to analyze fuels for contaminants such as sodium, potassium, vanadium, lead, calcium, silicon etc. and additives such as magnesium compounds. Atomic absorption spectroscopy (AAS) and various atomic emission spectroscopy (AES) techniques will be discussed and compared.

Abstract:
This work presents preliminary results of corrosion studies for three blades, one of the low pressure compressor and two of two different stages of the high pressure compressor of a gas turbine, which has been operating for 5,000 hours. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray diffraction (XRD), Electrochemical Impedance Spectroscopy (EIS) in aqueous solution containing chloride, and Atomic Absorption Spectrometry (AAS) were used to characterize the blades surfaces. The SEM and EDS results showed that the homogeneity and amount of contaminants, such as sodium, potassium, calcium, magnesium, chloride and sulphur are bigger in the high pressure compressor blade surfaces than in the low pressure compressor blade surface. The EIS results showed that the degradation process in turbine compressor blades increases with the temperature and pressure increase inside the compressors and depends of the blade composition. The low pressure compressor blade, which was made of a Ti base superalloy exhibited smaller corrosion resistance (smallest charge transfer resistance value (Rct)) than the two high pressure compressor blades, which were made of a Fe base superalloy. However, despite of its lower resistance to corrosion, after 5,000 hours of service, the low pressure compressor blade did not present pitting corrosion while the high pressure compressor blades did.
