The equilibrium and kinetics of copper(II) extraction from chloride solution with dioctyl pyridinedicarboxylate and commercial extractant ACORGA CLX-50 was studied. The measured dependencies show that the initial extraction rate and equilibrium constant strongly depend on the temperature and diluent for both extractants. The equilibrium and initial rate of extraction decrease as the temperature increases. The opposite effect of temperature is observed for dioctyl pyridine-2,4-dicarboxylate in homogeneous systems. In this case the rate of copper complexation increases as the temperature increases. The initial rate of reextraction increases as the temperature increases. Copper(II) is stripped from the complex with 0.1 M HCl with a rate significantly quicker for ACORGA CLX-50 in respect to dioctyl pyridine-2,4-dicarboxylate.
