An attempt was made to determine polarographically titanium, niobium, and tantalum where all these cations are present. The calibration curves for titanium determination were established when niobium and tantalum were present. However by this method niobium and tantalum separation was not possible. Calibration cuives were plotted for niobium and tantalum solutions where either one of these cations is present. In addition, a study on the polarographic behavior of zirconium and germanium is presented for determination purposes. Zirconium determinations were performed in nonaqueons modium (methanol) from 0.04 mu g up to 1 mg ZrO/sub 2/. The use of EDTA 0.1 M as supporting electrolyte makes possible the determination of 8 mu g to 1 mg of germanium. (auth)
