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. T

Abstract:

Drinking water is vital for life existence worldwide which is used on a daily basis. The quality of this drinking water however varies from one product to another. In this study, analysis of four heavy metals: Zn, Cu, Cd, and Pb were done by AAS technique in four water samples; Tap water, Well water, Faro bottle water and KSUSTA table water. The results of the study showed that Pb was not detected in the Tap, Well, and Faro Bottle water samples but was however detected in the KSUSTA Table water sample (0.954 mg/L) well above the limits of USEPA (0.015 mg/L), WHO (0.01 mg/L), and SON (0.01 mg/L

Abstract:

Atomic Absorption Spectroscopy (AAS) is the usual method for the direct determination of small amounts of manganese in plant materials (Christian & Feldman 1970; Heanes, 1981) and other substances (Carnrick, Slavin & Manning, 1981). However, it uses the highly sophisticated and expensive Atomic Absorption Spectrometer, which requires a reasonable degree of technician expertise, and is therefore not suitable for routine chemical analyses in Third World countries.

A procedure is developed for the determination of Cd, Cu, Mo, Pb, Te and Ni in natural and spiked water by Atomic Absorption Spectroscopy (AAS) after preconcentration on a coniine dithiocarbamate supported by polyurethane. The sorbed elements are subsequently eluted with 5 mol L-1HNO3and the acid eluates are analysed by AAS. A 20 mL syringe served as a chromatographic preconcentration column. The sorption recoveries of elements were higher in the order of 99%. The method is also applied successfully for the determination of Cu, Cd, Mo, Pb, Te and Ni in natural and spiked water samples.

Abstract:

A power-modulated (pulsed), radio-frequency glow discharge source by atomic absorption spectrophotometry (rf-GD-AAS) atomizer was used to evaluate the roles of applied power, pressure, orifice diameter, duty cycle, and power-on time in the production of gas-phase sample atoms. As expected, the response of the modulated rf-GD-AAS source generally followed the same trends as those exhibited by the more common continuous-powering scheme. The effects of discharge power and pressure on the observed plasma emission and absorbance transients are presented. Use of small duty cycles and higher instanta

Abstract:

The present paper reports a new method for the quantification of the Ni2+-capacity of an immobilized metal affinity chromatography (IMAC) material using near-infrared spectroscopy (NIRS). Conventional analyses using UV absorption spectroscopy or atomic absorption spectrometry (AAS) need to dissolve the silica-based metal chelate sorbent as sample pretreatment. In the first step, those methods were validated on the basis of an ideal homogenous NiSO4-solution and unveiled that UV with an intermediate precision of 2.6% relative standard deviation (RSD) had an advantage over AAS with an intermedia

Abstract:

Analyses of lubricating oils from aircraft engines, gear boxes and other lubricated mechanisms have been routinely performed by the military since the 1960's. The monitoring of the wear metal concentrations in the oil can lead to an early detection of abnormal wear and, consequently, the prevention of a malfunction or a complete failure of the aircraft. At the present time, almost all the analysis programs use atomic emission (AES) and/or atomic absorption (AAS) spectroscopy to determine elemental concentrations in the oils (1). These types of analysis require the close support of a laboratory

Abstract:

The trace element concentrations in high-purity graphites were determined by atomic absorption spectrometry (AAS) with the use of a modulated glow discharge atomizer. Glow discharge power was modulated at SO Hz to enhance sensitivity and to permit time-resolved atomic absorption measurements. The influence of discharge operating parameters including current, pressure, and plasma sampling on the analytical performance of this technique was investigated. This analytical technique was evaluated in terms of stability, sensitivity, reproducibility, and accuracy. The method of standard additions was

Abstract:

Minerals content of Citrus jambhiri (rough lemon) fruit was qualitatively and quantitatively analyzed using atomic absorption spectroscopy (AAS) and flame atomic emission spectrometry (FAES). The peel, moisture and ash contents of rough lemon were found to be 18.35%, 23.75% and 2.04% respectively. Vitamin C (ascorbic acid) of rough lemon juice was found to be 70.0 mg/100 g. The chemical composition of essential oil of rough lemon peel was determined. The major compound was found to be limonene (84.5%) followed by sabinene, β-myrcene, α-terpineol, 1,3-tetradecadiene and linalool.

Abstract:

Nanoparticles with controllable sizes of ferrite spinel CoFe2O4 were formed by thermal treatment of cobalt-iron glycerolate. Thermal behavior during the heating was studied by differential thermal analysis combined with thermogravimetry. The precursor, as well as the prepared nanoparticles, were analyzed by a broad spectrum of analytic techniques (X-Ray photoelectron spectroscopy (XPS), X-Ray diffraction (XRD), Energy dispersive spectroscopy (EDS), Atomic absorption spectroscopy (AAS), Scanning electron microscopy (SEM), and Raman spectroscopy). The particle size of nanoparticles was obtained

Abstract:

Natural diatomite was modified by manganese chloride via the low temperature hydrothermal route. The chemical properties and adsorption efficiency of the natural and the modified diatomite were characterized. The chemical compositions of the natural and the modified diatomite were determined by X-ray fluorescence spectroscopy (XRF) and energy dispersive X-ray spectrometry (EDXS). Morphology of the natural and the modified diatomite was investigated by scanning electron microscopy (SEM). The adsorptions of Cd (II) and Pb (II) ions onto the natural and the modified diatomite were determined by a
