| 摘 要： | Sommer曾提出用脉冲极谱测定镓和铟,灵敏度分别达到0.05ppm镓和0.1ppm铟。本文在前一工作的基础上,进一步研究了镓铟—茜素S络合物的吸附催化波。在0.26M氧化钾—0.08M乙酸钠(pH5)的底液中,当有1×10~(-4)M茜素S存在下,波高与浓度在0.01—0.4微克镓/毫升,0.004—0.4般克铟/毫升之间呈线性关系。峰电位分别为-1.13伏和-0.63伏(对S,C、E),因此可在同一底液中同时测定镓和铟。

An Oacillo-Polarographic Study of Aluminium-Gallium-Indium-Alizarine S complexes III Simultaneous determination of Gallium and Indium in ores |
| |
| Abstract: | The polarographic catalytic waves of gallium and indium have bean studied by oscillo-polarogrphy in potassium chloride-sodium acetatealizarin S at pH 5.0. The peak potential appears at -1.13 v (Vs. S. C. E) for gallium and -O.63 v for indium. The wave height is direct1y proportional to the concentration of gallium in the range of 1.5 × 10-7 M to 6 × 10-6 M and indium in range of 4 × 10-6 M to 4×10-6 M. This method has been used for simultaneous determination of trace gallium and indium in ores. |
