Physicochemical laws of liquid extraction of copper ions out of aqueous solutions by a mixture of oleic acid and triethanolamine

摘要

The physicochemical laws governing liquid extraction of copper ions out of aqueous solutions of a mixture of oleic add and triethanolamine in kerosene are investigated. It is established that the process of extraction is found in a kinetic region and that it is limited by the formation of a complex of copper ions with components of the extracting agent that solvate in the organic phase.
