| Abstract: | A bromopyrogallol red modified carbon paste electrode was used as a working electrode for the selective preconcentration of antimony(III). The composition of electrode- activated complex is Sb(III) : BPR = 1 : 1. The mechanism of electrode process was studied in detail. This method has been successfully applied to the determination of trace antimony(III) in Zinc electrolytic solution with satisfactory results. The detection limit is 2.0×10-8 mol/L. |
