Simultaneous determination of iron and copper in pregnant liquid solutions

Autor: M. Inés Toral, C. Paipa, E. Poblete

Publikováno v: Minerals Engineering. 19:1465-1468

A new method for the determination of Fe Total and Cu is proposed. The method is based on the formation of the iron and copper complexes with 5-sulfosalicylic acid (SSA), the optimal conditions were found, using SSA 5.1 g L −1 in the presence of am
