A sensitive anodic stripping voltammetric procedure at the bismuth film electrode (BiFE) is presented for analysis of Sn(IV) in the presence of Pb(II). For the first time Sn(IV) and Pb(II) signals are resolved at the BiFE allowing quantification of Sn(IV) in the absence and presence of Pb(II) and in simultaneous determination of both trace metals. The optimised oxalic acid – CTAB method produced a...
