【摘要】 本文通过七种硫醚从盐酸介质中萃取金的行为及其影响因素，讨论了硫醚结构与萃取过程热力学函数的关系，用多种实验方法确定了被萃配合物的化学组成为AuCl3R1SR2（其中R1与R2为相同或不同的烃基）．萃取过程属配体取代反应．还考察了贵金属离子钯（Ⅱ）、铂（Ⅳ）对萃取金（Ⅲ）的影响，表明本文所选用的试剂具有较高的选择性．更多还原

【Abstract】 The extraction of gold(Ⅲ ) from hydrochloric acid medium with seven thioethers has been studied in various conditions. the relationships between structures of organic sulfides and thermogynamic functions of extraction reactions have also been discussed. The composition of extracted complexes is determined by many methods of the extracting chemistry (Slopes,etc. ) and it is proposed that the mechanism of extraction reactions be a substitution reaction.更多还原
