摘要： 采用离子选择电极作为分析手段,用恒界面搅拌法考察了多种因素对季铵盐N263-正辛烷由氯化物介质中萃取钯(Ⅱ)动力学的影响,从实验结果推论出萃取过程为界面化学反应控制型机理。对酸度、添加剂的影响也作了讨论。

Abstract: The extraction kinetics and mechanism of palladium (Ⅱ) from chloride medium with quaternary ammonium salt(N263 ) were studied by means of PVC-membrane Pd(Ⅱ) ion selective electrode and stationary interface stirring cell,The experimental results show that the extraction process may be controlled by the following interlace reaction.where AC1,(i) and (o) repesent N263,interface and organic phase respectively.The influences of temperature,acidity,and added substance (n-octoh) in the organic phase on the extraction rate are also discussed.
