Abstract

Electrochemical behavior of N,N-diphenyl- and N,N'-diphenylthioureas, as well as Te (IV) has been studied in sulphuric and hydrochloric acids media. It has been shown that amperometric titration can be carried out both by the reagents oxidation and Te (IV) restoration current. Optimal conditions for amperometric titration: acidity, concentrations of reagents, range of Te (IV) determined concentrations have been revealed. Mathematical treatment of experimental data has been done. The method has been applied for tellurium determination in the Te containing ore.
