【 摘 要 】

References(21)Cited-By(30)A kinetic study of copper extraction with reagent-grade N-8-quinolyl-p-dodecylbenzenesulfonamide was carried out by using a stirred transfer cell, along with studies of the distribution and interfacial equilibria of the extractant between the organic and aqueous solutions at 303K. The rate of copper extraction was analyzed by a model of the interfacial reaction between the adsorbed extractant (HR) and the adsorbed copper complex (CuR+) accompanied by the mass transfer steps of each species. The experimental results show good agreement with the results calculated by use of this interfacial reaction model, concerning the initial extraction rate and the extent of copper extraction over a wide range of experimental conditions.
