Abstract
The performances of trioctyle-phosphine oxide (TOPO) and tributyle phosphite (TBP’) in the removal of Cu and Co from aqueous wastes was investigated. The optimization study achieved highlighted the occurrence of a synergy effect in the Cu liquid-liquid extraction using a mixture (TOPO + lauric acid). Extraction yields of ca. 75% by cycle were obtained.
