摘要
笼形聚偕胺后树脂分别用硼酸、硝酸、磷酸、硫酸和氢卤酸处理后,对Ag+、AuC、IrC、NdC、和PtC离子的吸附容量都发生显著的差异,吸附能力与处理酸的阴离子在偕胺肟基上的结合程度有关。研究了硼酸处理树脂对上述离子的吸附动力学,讨论了吸附机理。
The cage polyamidoxime resins were treated with boric acid, nitric acid, phosphoricacid, sulfuric acid, hydrofluoric acid, hydrochloric acid and hydroiodic acid, respectively.The adsorbents obtained (HX/ACAO) are widely different in adsorption capacity for Ag, AuC, IrC, PdC, and PtC ions. It is considered that the adsorptivity depends upon the extent of the acid anions combine with the amidoxime groups. The adsorption kinetics was investigated and the mechanism was discussed.
