摘要
研究了胺醇萃取剂Ｎ２１２５自盐酸介质中萃取金的性能，萃取率随酸度增高而增大。用等摩尔系列法、饱和法及斜率法测定萃合物组成为（Ｎ２１２５）２ＨＡｕＣｌ４，通过ＩＲ、ＨＮＭＲ波谱探讨萃取金的机理为离子缔合，氮原子主要参与配位，而－ＯＨ中的氧原子不发生配位。
Extraction of Au(Ⅲ) by N2125 from hydrochloric acid medium has been studied. The extraction capability is increased with the increase of hydrochloric acid concentration. It is showed by slope method, continuous alternate method, and saturation method that the composition of extracted species is 2HAuCl 4. IR and HNMR studies show that the mechanism of extraction of AuCl - 4 is regarded as ion-association through coordination with N but not with oxygen atoms in -OH.
