摘要：

The extraction of copper(II) ions from ammonia solutions with a new beta-diketone extractant, DX-510A, has been studied. Kinetic features of the copper(II) extraction and back extraction have been established: the reaction orders have been determined, and extraction and stripping rate constants have been calculated to be k (e1) = 4.14 x 10(-2) s(-1) and k (be1) = 3.20 x 10(-2) s(-1), respectively. It has been demonstrated that the extraction of copper(II) ions is not accompanied by the coextraction of ammonia. The type of extracted complex has been determined and its formula has been suggested.
