Determination of trace gold and silver by iron replacement - AAS 铁置换原子吸收光谱法测定微量金和银
The technical progress in recovery of copper from leaching solution of low-grade copper ores in recent years was reviewed in this article. Some technologies such as iron replacement, solvent exttaction-electrowinning, liquid membrane separation electrowinning were briefly evaluated. 本文评述了近年来国内外从低品位铜矿浸出液中采用铁屑置换法、溶剂萃取一电积法、液膜分离一电积法等工艺回收铜的技术进展。
Iron line replacement method is used to recovery metal silver from silver sulfate in COD waste liquid, and it is reused to analyze, so analysis cost and environment pollution are decreased. 对COD废液中的硫酸银,采用铁线置换法回收金属银,进行循环使用,降低了分析费用,减小了环境污染。
