【 摘 要 】

Studies were conducted on the extraction of copper, nickel and zinc from their sulphate solutions using [bis (2,4,4- trimethylpentyl) phosphinic acid] (Cyanex 272, HA) as an extractant. Effect of various parameters, such as equilibrium pH, extractant concentration, sulphate and acetate ion concentration was investigated. The slope analysis method was used to determine the nature of extracted metal complexes. For the extraction of metal [M(Ac)(HA2).2HA] species was formed.
