Abstract:
Abstract Forms of copper that are highly soluble in aquatic environments are used as chemical reagents in a variety of industries, especially copper complexes. Wastewater containing copper complexes can be difficult to treat and analyse. Normally, flame atomic absorption spectrophotometry (FAAS) is a favourable technique for analysing metal ions in wastewater, but is less reliable for copper analysis owing to the influence of copper oxides. To solve this problem, it is necessary to adjust the atomization and delay times. The objective of this study was to use FAAS to accurately determine the q

The influence of the presence of an organic solvent on the determination of trace elements by flame atomic absorption spectrophotometry (FAAS) was investigated under different experimental conditions. The obtained results show that the effect of organic solvents on the signal intensities depends not only on the physical properties of the solution but on the analyte properties too. The extent of the effect is also very dependent on the construction of the nebulization system as well as on the stoichiometric flame composition. These facts indicate the very complex mechanism of the effect and dem

ABSTRACT Toxicological studies have shown that the degree of toxicity of some elements depends on the chemical form in which the element is present. Chromium (III) is considered as an essential micronutrient for human whereas chromium (VI) is a potentially carcinogenic agent. So the speciation of inorganic chromium in environmental samples is required for accurate assessment of pollution levels. The chromium content in natural water is usually very low, and a preconcentration is often necessary prior to the determination. A sensitive and selective preconcentration and speciation procedure

The concentrations of heavy metals (Cd, Cu, Fe, Ni, Pb, Zn) were measured in water, and fish samples caught from the pond at Fishery Park in Unicoi County, TN. The water samples were collected once a week for 8 weeks. The amounts of metals in the muscle tissues, gill, and liver of the two fish species were measured. This was to determine if any correlation exists between the metal contents in water and those in the fish samples. The concentration ranges for the heavy metals found in the water samples are as follows: Zn 0.04-0.13; Cu, 0.00-0.00; Pb, 0.00-0.59; Cd, 0.0067-0.0071; Fe, 0.208-0.512

Abstract:
A new method for extraction of titanium dioxide (TiO2) from cosmetic matrices using borate salts for its quantification by flame atomic absorption spectroscopy (FAAS) was developed and validated. Following International Commission for Harmonization (ICH) and the United States Pharmacopeial Convention (USP) guidelines, the parameters of the method considered in this study were specificity, linearity, sensitivity, precision, and accuracy. In addition, critical factors of the method were assessed using a Youden–Steiner model. The method was able to differentiate the titanium signal from matrix and background signals, for which it is considered specific. The method is also linear for all cosmetic matrices and the raw material in the range 20–80 ppm with LOD and LOQ around 2 ppm and 7 ppm, respectively. Repeatability and intermediate precision were below 5.0%RSD, and Global Reproducibility was below 8.0% RSD. A digestion step free of HF or strong oxidizers makes this method a safer and easily transferable alternative to classical methods for quality control. It is thus a convenient tool for routine analysis of cosmetic products that need to comply with current regulations to ensure the safety of consumers and to guarantee batch-to-batch quality.

Morine ligand and Triton X-100 as surfactant was used for the recovery of Ti. The optimum results found were applied on ash samples. As a result of the study, while the optimum recovery values varied between 96-99% , the relative standard deviation values were found to be less than 10%.
