A Research of Polarographic Adsorption Catalytic Wave of Germanium and Its Application for Determination of Germanium in Ores |
| |
| Abstract: | The polarographia behaviour of germanium complex with alizarin-S has
been studied in this paper. The germanium complex: gives a high sensitive
wave at dropping-mercury electrode at-0.68 v. The optimum condition for
determination of Ge is 0.2 M ammonium chloride, 2% formic acid, and 0.001
M. alizarin-S. The linear relationship between the peak height and concentration
of germanium occurs in the range of 0.005-0.8 ppm. Some interfering ions
(anodic and cathodic) are tested. |
