考查水相酸度、氯离子浓度、有机相中萃取剂浓度以及体系温度对伯胺N1923—苯、氯仿从氯化物介质中萃取Pd(Ⅱ)的影响。结果表明,在低负载时,萃取反应亦为阴离子交换反应。
The effects of aqueous phase acidity, chloride ion concentration, extractant concentration in organic phase and system temperature on the extraction of Pd (Ⅱ) from primary amine N1923-benzene and chloroform from chloride medium were investigated. The results show that at low loading, the extraction reaction is also an anion exchange reaction.
