A sensitive and selective adsorptive stripping voltammetric method was employed to determine traces of tin in water samples. The spontaneously formed tin complex with 2,5-dichloro-1,4-dihydroxy-3,6-benzoquinone (chloranilic acid) is adsorbed at the surface of a mercury drop electrode. The analyte ca

This paper describes a new voltammetric procedure for the inorganic speciation of As(III) and As(V) in water samples. The procedure is based on the chemical reduction of arsenate [As(V)] to arsenite [As(III)] followed by the voltammetric determination of total arsenic as As(III) at the hanging mercu
