IUPAC reference method for analysis of nickel in serum and urine by electrothermal atomic absorption spectrometry.

Elimination of Chemical and Spectral Interferences in Measurement of Trace Elements in Urine and Blood by Combined Electrodeposition-Electrothermal Atomic Absorption Spectrometry

A combined electrodeposition-ETAAS technique has been applied to the analysis of Pb, Cd, Co, Ni, Cr and Mn in biological samples in order to overcome interferences and to minimize sample pretreatment. It requires minimal sample preparation with the electrolysis process aiding partial decomposition of the organic matrix, adequate for the release and deposition of trace elements. In an initia...

Determination of Cadmium by Electrothermal Atomic Absorption Spectrometry after its Separation and Preconcentration by Syringe to Syringe Dispersive Liquid Phase Microextraction-Solidified Floating Organic Drop

The application of syringe to syringe dispersive liquid phase microextraction-solidified floating organic drop was extended for the separation and preconcentration of trace amounts of cadmium ions from water and cereal samples. The extracted cadmium was quantified by electrothermal atomic absorption spectrometry. Factors affecting the complex formation as well as microextraction efficiency such...

Rapid analysis of nickel in serum and whole blood by electrothermal atomic absorption spectrophotometry.

A method is described for analysis of nickel in serum and heparinized blood. After the sample has been subjected to protein precipitation with nitric acid and heat, nickel in the protein-free extract is measured by electrothermal atomic absorption with Zeeman background correction. The method is more sensitive, rapid, and convenient than previous techniques, and less subject to nickel contamina...

Determination of arsenic in biological fluids by electrothermal atomic absorption spectrometry.

A procedure for the determination of the total content of arsenic in urine, serum and blood by electrothermal atomic absorption spectrometry (ETAAS) is described. Zeeman correction is used to compensate the high background signals. The samples are diluted (1 + 1 for urine and 1 + 3 for both serum and blood samples) in a medium containing 0.1% w/v Triton X-100 before being introduced directly in...
