The removal and recovery of Cu, Cr and Zn from plating rinse wastewater using supported liquid membranes (SLM) are investigated. SLMs with specific organic extractants as the liquid membrane carriers in series are able to remove and concentrate heavy metals with very high purity, which is very promising for recycling of heavy metals in the electroplating industry. A technical comparison between the membrane process and the conventional chemical precipitation process was made.
研究了使用支撑液膜（SLM）从电镀漂洗废水中去除和回收铜、铬和锌。以特定有机萃取剂作为液膜载体的串联支撑液膜能够以非常高的纯度去除和浓缩重金属，这对于电镀行业中重金属的回收非常有前景。对膜工艺和传统化学沉淀工艺进行了技术比较。
