【摘要】 研究了Ｂｉ（Ⅲ）－Ｐｈ（Ⅱ）与八种变色酸双偶氮型试剂的示波极谱行为。其中五种含多卤素取代基的不对称结构试剂与Ｂｉ（Ⅲ）－Ｐｈ（Ⅱ）生成异核络合物，用单扫示波极谱法得到灵敏的络合吸附波。测定了络合物的组成，研究了电极过程和提出了电极反应机理．用巯基棉吸附和分离，可消除共存离子的于扰，建立了测定痕量铋的方法，用于铜合金和人发的分析，结果满意．更多还原

【Abstract】 In the medium of HCI, Bi(0283)and Ph(Ⅱ) with some biarsenazo dyes peduced a high sensitive polaroglaphicadsorptive wave of the isonuclear compact. aam odection limit was 1.5×10-9mol/L for Bi(Ⅲ). The co~itkin of bonudcarcomplex was odedtal. The reversibility of elctrode precoess,the character of adsorption and the mechanism of electrode reac-tion were studied,A series of comtants and Parameters were calculated.The proposed method has been applied to thedetermination of trace bismuth in copper be alloy and hair with satisfactory results.更多还原
