【摘要】 本文研究在盐酸介质中以三辛胺氮氧化物（分子式为（C₈H）O,简称TOO）,萃取金（Ⅲ）的行为及其机理。用等温曲线、斜率、Job法、紫外光谱、摩尔电导、红外和核磁共振等方法确定了萃合物的组成,表明系由两个TOO分子和H⁺发生氢键作用,并与AuCl形成离子缔合物,其组成可表述为[TON0…H⁺…0NOT]AuCl₄-。更多还原

【Abstract】 The extraction of gold(Ⅲ) from hydrochloric acid medium with tri-octylamine oxide(TONO) in benzene solution has been studied in various conditions. The chemical composition of extracted species is determined by the methods of Job’s, extraction isotherms curve, slope ratio, molar conductivity, UV and IR spectra. The extraction is found to proceed according to the reaction ofH+ + AuCl4- + 2TONO(o)=[TONO…H+…ONOT]·AuCl4-(o)The possible structure of extraction complex has been discussed. The preliminary study of the industrial value for the extraction of gold(Ⅲ) has also been made.更多还原
