N. S. Ivanov, A. B. Bayeshov, B. E. Myrzabekov and S. S. Bitursyn

The process of electroreduction of Te(IV) on the glassy carbon electrode in an alkaline medium has been presented. The influence of main parameters such as the potential sweep rate, the concentration of Te(IV) ions, and the temperature of the electrolyte were studied. It is shown that in alkaline solutions, Te(IV) recovering with a subsequent transition phasically into solution politellurid and sodium telluride. It was found that the cathodic process is strongly dependent on the composition and temperature of the electrolyte of the solution.
