摘要
用胺醇萃取剂NTAB-182在盐酸介质中萃取钯时,稀释剂和萃取剂浓度及萃取平衡时间均有影响。用HNO_3反萃取钯,由连续变换法和饱和法及元素分析法确定萃合物的组成,还确定其萃取机理为离子缔合机理,萃取反应主要在界面上进行。
The extraction of PdCl_4 ̄(2-) from hydrochloric acid with NTAB-182 has been studied. The optional conditions of the extraction and backex traction are determined experimentally.The composition of the extracted complex has been studied by the methods of saturation, molecular ratio,and elemental analysis.The mechanism has been determined by IR and UR. It is found that the extraction reactions are mainly taken place on the interface of NTAB-182 and HCl based on the interface nature study.
