Adsorção de níquel e cobalto em resina de troca iônica como alternativa para o tratamento de licor de lixiviação

Abstract

Estudou-se o emprego da resina PUROLITE S-930 como substrato para a remoção de níquel e cobalto de soluções sulfúricas. Ni 0.28 mol/L, at 70°C and q max Co 0.18 mol/L, at 60°C Abstract A study concerning the resin PUROLITE S-930 as a substrate to remove nickel and cobalt from sulphuric solution is herein presented. The influence of nickel and cobalt concentrations was studied, and the results have shown a greater selection of the resins for solutions rich in nickel (Ni 600 mg/L -Co 800 mg/L). The adsorption isotherms showed an increase in the resin adsorption capacity at higher temperatures (q max
