[0002] Electroplating sludge is a solid waste containing heavy metal hydroxides generated during the treatment of electroplating wastewater. It has a complex composition and mainly includes heavy metal compounds such as chromium, iron, nickel, copper, zinc and their soluble salts. Extractants are required in the treatment of electroplating sludge. The role of the extractant in the treatment of electroplating sludge is to achieve selective separation and concentration of heavy metals for subsequent recovery and utilization. The extractant is a weakly acidic solution and needs to be saponified before use.
