摘要：
The researches of electrochemical refining of technical selenium obtained at the processing sulfuric sludges of chemical and pulp-paper productions were presented. The method was developed for electrochemical separation of selenium and tellurium providing the transformation of selenium into solution and its subsequent deposition with obtaining of elementary selenium containing not more than 5.10(-5)% of tellurium.
