铬渣的稳定化研究

Chemical stabilization treatment of chromium slag

探讨了铬渣稳定化的一种简单方法。利用硫酸亚铁为稳定剂与铬渣相混合进行稳定化处理，铬渣中的水溶性六价铬被亚铁离子还原而降低毒性。经浸出实验表明，处理后铬渣的六价铬的浸出量在容许范围内。

A simple method of stabilizing chromium slag with FeSO 4 was investigated.The experimental results showed that the toxicity of the treated chromium slag was greatly reduced,and the concentration of Cr 6+ met the National Standard.
