Differential pulse stripping voltammetry was applied in the determination of mercury in urine samples. The mercury in the samples was oxidized to Hg(II) using bromine and KMnO 4 . Hg(II) was reduced by NaBH 4 to the metallic state and volatilized using nitrogen as the carrier gas. The gas containing

A rapid, simple, and reproducible method for determination of iron in biological material is suggested using the oxidation of p-phenetidine hydrochloride with hydrogen peroxide in a reaction catalyzed by Fe(lII) and activated by f,lO-phenanthroline. The high sensitivity of the reaction allows a sing
A simple indirect method making use of 3,4-dihydroxyphenylalanine (L-dopa) as an electroactive complexation ligand for the determination of aluminum in biological samples at neutral pH on glassy carbon working electrode with differential pulse voltammetry (DPV) is reported. This method relies on the
## Abstract In this work, a new and simple microโextraction method termed __graphite adsorption bar microโextraction__ was developed, for the first time, for electrothermal vaporization inductively coupled plasma mass spectrometry (ETVโICPโMS) determination of trace Cd, Hg and Pb. In this method, t
