由混合电镀污泥硫酸浸出液选择性沉淀分离铬的研究
Recovery of chromium from sulphuric acid leaching solutions of mixed electroplating sludge by selective precipitation
摘要
Abstract
The recovery of Cr from the sulphuric acid leaching solutions of mixed electroplating sludge (MES) is studied. After the removal of Cu by solvent extraction, the selective phosphate precipitation is applied for the separation of Cr from Fe, Ni and Zn in the MES leaching solutions. The experimental results show that the precipitation of Cr can be carried out stably and effectively and the concentration of Cr in the solutions can be lowered down to about 0.04 g/L. Cr is efficiently enriched in the precipitates which contain 13% of Cr, 0.4 %of Ni, 0.1%of Fe and 0.2%of Zn,respectively,and could be further recovered as economic products.关键词
