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 reversible intermittent flow-injection procedure is proposed for the automated determination of mercury in sediments and vinasses by cold vapor atomic absorption spectrometry, CVAAS. Solutions of sample and stannous chloride are carried by two air streams and sequentially injected into the generat
