| Abstract: The extraction of gold(Ⅲ) from hydrochloric acid medium with some symmetric and asymmetric thioethers has been studied in various conditions. The relationships between organic sulfide structures and the thermodynamic functions of extraction reaction have also been discussed.The composition of extracted complexes is determined by many methods of the slopes and Job's etc.,It is proposed that the extraction reaction is substitution mechanism one. The reaction could be expressed as follows:HAuCl4+R1SR2(o)⇔AuCl3·R1SR2(o)+H++Cl-where R1 and R2 is alkyl- or aryl-. |
