electrodos electro precipitation
An electro-precipitation method is proposed for the treatment of synthetic (2654.4 mg L −1 total Cr, pH 3.9) and real tanning effluents (2775 mg L −1 total Cr, pH 4.0) containing elevated concentrations of Cr(III). Aluminum and copper anodes are thermodynamically (Pourbaix-type diagrams) and electrochemically evaluated in the synthetic electrolyte, as potential candidates to generate the
