本文论述了Cyanex471X萃取剂从盐酸溶液中萃取An（Ⅲ）的有效性。萃取体系为吸热反应并受试验参数如萃取剂浓度、有机稀释剂和盐酸浓度的影响。在盐酸浓度1～3mol／L范围内获得最大金萃取率。平衡负载等温线表明，有机相中[Cyanex471X]／（An（Ⅲ）]摩尔比近于1．5，萃合物化学式可以表示为HAuCl4L（lgK0ext＝3．79）和HAuCl4L2,L代表有机萃取剂。该体系看来对选择性萃取金是适合的。金只能以硫代硫酸钠溶液反萃取，相应的反应也是吸热反应。
This article discusses the availability of Cyanex 471X extractant to extract An (III) from hydrochloric acid solution. The extraction system is endothermic and is influenced by test parameters such as extractant concentration, organic diluent and hydrochloric acid concentration. In the concentration of hydrochloric acid 1 ~ 3mol / L maximum gold extraction rate. The equilibrium loading isotherms indicate that the molar ratio of [Cyanex471X] / (An (III)] in the organic phase is near 1.5 and the chemical formula of the complex can be expressed as HAuCl4L (lgK0ext = 3.79) and HAuCl4L2, where L represents the organic extractant The system appears to be suitable for selective extraction of gold, gold can only be back-extracted with sodium thiosulfate solution and the corresponding reaction also endothermic.
