Simultaneous separation of nickel and copper from sulfuric acid using chelating weak base resins

Autor: Mª Fresnedo San-Román, Laura Ulloa, Eugenio Bringas

Publikováno v: Journal of Chemical Technology & Biotechnology. 95:1906-1914

BACKGROUND: The management of industrial spent acids containing metals to be potentially recovered for further reuse is within the scope of circular economy principles In particular, spent sulfuric acid solutions are usually treated by precipitation
