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.
