Abstract
The physicochemical properties of anti 2-hydroxy-5-nonylacetophenone oxime, the active species of SME 529, were measured in the system consisting of Dispersol, a commercial organic diluent, and aqueous sulphate solution. The initial extraction rate of copper with this chelating agent was studied by use of a transfer cell with a free flat interface. The effects of the concentrations of copper, proton and extractant on the initial extraction rate were reasonably interpreted by a mechanism where by the extraction rate is determined by the secondary complex formation and the diffusion of extractant in the organic phase.
