摘要: 以PVC膜钯离子选择电极作为检测手段,用恒界面搅拌池法研究了三辛胺从氯化物介质中萃取钯(Ⅱ)的动力学。采用计算机模拟的方法求出速率常数值,讨论了酸度、温度、添加剂等因素的影响。

Abstract: The extraction kinetics and mechanism of palladium (Ⅱ) from chloride medium with trioctylamine (TOA) were studied by means of PVC-membrane Pd(Ⅱ) ion selective electrode and stationary interface stirring cell. The experimental results showed that the extraction process is controlled by the following reactions,(这里有图片198704-296-1.gif)where (i) and (o) represent the interface and the organic phase, respectively. The values of k1, k-2and k2/k-1were calculated by computer. The influences of the temperature, acidity and added substance (n-octoh) in the organic phase on extraction rate are also discussed.
