Abstract

Invenţia se referă la un procedeu pentru decontaminarea soluţilor poluate cu diferite elemente metalice, şi constă într-o primă etapă (1) de dizolvare, în mediu bazic, a solvenţilor respectivi, în vederea dizolvării selective a elementelor metalice ce trebuie îndepărtate. In continuare, se aplică o altă etapă de cementare (II) a dizolvantului prin schimbul cu zinc metalic, după care se aplică o etapă (III) de electroliză a soluţiei rezultate din etapa de cementare (II), obţinându-se zinc sub formă de pudră, care poate fi recirculat parţial sau total în procesul tehnologic.
