【摘要】 研究了锑与碘化钾和罗丹明类染料在HAC-NaAc缓冲溶液(pH5.6)中的极谱行为,探讨了反应机理,提出痕量锑的测定方法。线性范围在锑浓度为0.5~2000ng/ml,检出限0.33ng/ml。

【Abstract】 The electrochemical behaviour and the current property of antimony based on the formation of ion-associate complexes of Sb(Ⅲ) with iodide and rhodamine basic dyes are investigated in HAc-NaAc buffer solution (pH 5.6).The mechanism of related reactions is discussed.A new simple,sensitive and selective oscillopolarographic method is established for the determination of trace antimony. The detection limit was 0.33 ng/ml.
