本文研究某些高分子量叔胺(N_(235)和TBA)和氯化三烷基甲铵(N_(263))从盐酸溶液中萃取金的行为,考查了水相酸度、被萃金属浓度、萃取剂浓度、温度和共存金属离子对萃取的影响。用等温线法、斜率比法和紫外吸收光谱法等确定了萃合物的组成和萃取平衡的机理,表明萃取过程属于阴离子交换反应,萃合物金与试剂之比为1∶1。
In this paper, some high molecular weight tertiary amines (N_ (235) and TBA) and trialkylammonium chloride (N_ (263)) were extracted from the hydrochloric acid solution. The effects of aqueous phase acidity, extracted metal concentration, Effect of extractant concentration, temperature and coexisting metal ions on extraction. The composition of extraction complex and the mechanism of extraction equilibrium were determined by isotherm, slope ratio and ultraviolet absorption spectroscopy. The results indicated that the extraction process belongs to the anion exchange reaction. The ratio of gold to reagent in extraction mixture is 1: 1.
