摘要
研制了采用溴邻苯三酚红(BPR)作修饰剂的碳糊修饰电极,并采用所制备的电极做工作电极建立了测定锑的 方法。测定了电活性络合物的组成,并探讨了电极反应机理。方法已用于锌电解液中痕量锑的测定,结果满意。检出限为2. 0×10-8mol/L。
A bromopyrogallol red modified carbon paste electrode was used as a working electrode for the selective preconcentration of antimony (Ⅲ) . The composition of electrode complex was determinated. The mechanism of electrode process were studied in detail. This method had been successfully applied to the determination of trace antimony(Ⅲ) in Zinc electrolytic solution with satisfactory results. The detection limit is 2.0×10-8mol/L.
