Study of the electrochemical behaviour of selenium in biselenium electrolytes

Article preview

A thermodynamic analysis of the system Se – H 2 O was prospect. Plotted dependences the concentrations of selenium oxyanions from the pH of the solution and polarization graphs for various materials of the anode. Draw conclusions about the regularities of selenium electroextraction from selenium solutions.

Исследование закономерностей электрохимического выделения селена при переработке шламов электролиза меди

Article preview

В настоящее время производство редких халькогенов и благородных металлов осуществляется при переработке сульфидного полиметаллического сырья, преимущественно из шламов электролиза меди и никеля. Рассматривается возможность извлечения селена из щелочных растворов с использованием электролиза. Выполнен расчет выбора pH исходного раствора. Приводятся результаты поляризационных измерений осаждения селена из селенитно-биселенитных растворов. Сделаны заключения о возможности получения селена с использованием электролиза.
