Rapid polaropraphy with the mercury film electrode was applied to the simultaneous determination of Cu2+, Pb2+, Cd2+ and Zn2+ in water. When these ions were electrolyzed in 0.15M NH4Gl medium for 10 min. at -1.3V (VS. Ag- Hg electrode), the metals were elcctrodeposited on a mercury film electrode, and an anodic dissolution curve was recorded by an X-Y functional recorder from -1.3V to -0.1V. The peak heights were linear with concentrations within the range or 10-6M-10-8M for Cu, Pb, Zn and of 10-6M-10-9M...

The peak heights were linear with concentrations within the range or 10-6M-10-8M for Cu, Pb, Zn and of 10-6M-10-9M for Cd. This method is suitable for the determination of trace amounts of these elements in water.

快速极谱仪与汞膜电极联用,阳极溶出伏安法同时测定水中铜、铅、镉、锌。在O.15MV氯化铵介质中,调节pH至5.5,于一1.3伏电解10分钟(对Ag-Hg电极),这些金属便电沉积在汞膜电极上,并用记录仪于-1.3伏~-0.1伏记录阳极溶出曲线。10~(-6)M~10~(-8)M的铜、铅、锌和10~(-6)M~10~(-9)M的镉,其浓度与峰高呈线性关系。此法适用于测定水质中的这些痕量元素。

Possibility of the simultaneous determination of trace metals (Cu, Pb, Cd, Zn) by both anodic stripping voltammetry (ASV) and differential pulse anodic stripping voltammetry (DPS) at a rotatable glassy carbon electrode coated in situ with a thin mercury film was studied. Experimental results showed that the difficulty of simultaneous determination of those metals was connected with the formation of intermetallic compound in amalgam, in particular with the interaction of Zn and Cu. It is not difficult to determine simultaneously Cu, Pb and Cd or Zn, Pb and Cd in non—polluted enviromental samples. For the solution with Cu~(2+), Zn~(2+), Cd~(2+) , Pb~(2+) a new peak before Cu peak is displayed when ASV is used.It is a stripping peak of Zn in Zn_xCu_y. Nonetheless it is possible to determine four metals by ASV simultaneously. When DPS is used the deposition time can be shortened.The methode of the simultaneous determination of Cu, Pb, Cd and Zn was applied to examine the quality of distilled water and tap water.

本文用线性扫描阳极溶出伏安法(ASV)和微分脉冲阳极溶出伏安法(DPS)研究了在同位镀汞玻璃碳电极上同时测定铜、铅、镉、锌的可能性。实验证明同时测定这些离子的困难在于汞齐中形成金属间的化合物;干扰主要取决于铜和辞在汞齐中的相互作用;对一般未污染的环境样品用ASV或DPS同时测定铜、铅、镉或锌、铅、镉不会产生固难;用ASV同时测定铜、铅、镉、锌时在铜的溶出峰前出现一个铜辞化合物中辞的溶出峰,按本文所提出的测量峰电流的方法可以同时测定上述四种离子;用DPS可以用较短的富集时间同时测定这些离子。所制定的方法应用于鉴定蒸馏水及饮用水质量发现,由电加热蒸馏水器得到的蒸馏水会带来铜、铅的污染;济南地区各自来水厂水源中上述离子的含量大大低于国家规定的生活饮用水质标准。

A procedure for the anodic-stripping semidifferential electroanalytical simultaneous determination of Cu, Pb and Cd in activated carbon has been developed. With 0.1M KNO3-0.01M sodium tartrate (pH≌4) as supporting electrolyte, Cu, Pb and Cd give well-defined neopolarograms. The linear calibration curves are obtained for 1.0 × 10~(-9)-1.0 ×10~(-7)Cu(Pb)g/ml and 1 .0 × 10~(-l0)-1.0 × 10~(-7)Cdg/ml. The amount of Cu, Pb and Cd is determined by the standard addition method.

A procedure for the anodic-stripping semidifferential electroanalytical simultaneous determination of Cu, Pb and Cd in activated carbon has been developed. With 0.1M KNO3-0.01M sodium tartrate (pH≌4) as supporting electrolyte, Cu, Pb and Cd give well-defined neopolarograms. The linear calibration curves are obtained for 1.0 × 10~(-9)-1.0 ×10~(-7)Cu(Pb)g/ml and 1 .0 × 10~(-l0)-1.0 × 10~(-7)Cdg/ml. The amount of Cu, Pb and Cd is determined by the standard addition method. It is found that 1000-fo1d Al(Ⅲ), Ca(Ⅱ), Mg(Ⅱ) and 50-fo1d Cr(Ⅲ ), Fe(Ⅲ), Mn(Ⅱ) do not interfere with the determination under the selected experimental conditions.
