Abstract

Electrode behaviour of tellurium (IV) in the presence of different backgrounds has been studied. It has been shown that it is more preferable to carry the amperometric titration at +1 V by means of reagent oxidation current. It has been shown also that chemical interaction corresponds to the 1:4 molar ratio of the reacting components and takes place with reduction of tellurium (IV) to tellurium (II). Optimal conditions for determination: acidity, concentration ranges for tellurium, influence of accompanying ions have been revealed. Mathematic statistic treatment of obtained experimental data has been carried out.
