摘要:
采用以草酸为还原剂的氧化-还原法,在溶液温度为50~70℃,pH为3~5的条件下,回收与提纯电镀挂具上的镀金层,金的回收率可达97.9%,纯度为98%以上.
Abstract:
For recovering and purifying gold as the polating metal from electropolating hangers,redox reaction with oxalic acid as reducing agent is adopted. When the hanger keeps in temperature of 50~70 ℃ andpH= 3~5.9% gold with a purity over 98%can be recoveted. A
