| 摘 要： | 铜、铅、锡是水质中经常需检测的元素,据文献1—3]报道,分析时,它们相互干扰较大,需预先分离,步骤较烦。为此,木文提出在1:1 HOAc-NH_4OAc及0.006％铜铁试剂(Hucp)体系中以导数极谱法同时测定水中Cu、Pb、Sn,它们的峰电位分别为-0.24、—0.60及—0.76 V(vs.SCE)。方法简单、快速、选择性也好。最低可检测到4.0×10~(-9)gm1~(-1)的Cu.Pb.Sn。方法应用于测定近岸海水、矿泉水及电镀废水中三个离子可得到满意结果,变动系数均低于10％。现将实验结果及讨论分述如下:

| Abstract: | This Paper simultaneous determinations of the dissolered species of Cu, Pb and Sn in water made by derivative Polarographic wave.In a buffer solu tion of 1 : 1 HOAc-NHtOAc at PH 5.0-5.5 containing 0.0052% Cupferron (Heup), by ustng sweep ocilloPolarograPhy. there;oecur sens'itive adsorP tive complex waves of Cu-Hcup, pb-Hcup and Sn-Heup. The Peak Potential of derivative wave are -0.2V-0.60 and-0.76 V (vs.SCE)resPectively. This method is quick, Simple, convenient one and is suitable for the analysis of verious kinds of water. |
