摘要： 三辛胺(TOA)从盐酸介质中萃取、富集金,已应用于原子吸收光谱法测定金,其高灵敏度及选择性使该方法成为金的十分理想的测定方法。本文考查了TOA从盐酸介质中萃取金(Ⅲ)的机理,试图对金(Ⅲ)的萃取分离及测定提供理论依据。

关键词: 金, 萃取, 三辛胺

Abstract: The extraction of Au (Ⅲ) with trioctylamine (TOA) in carbon tetrachloride from hydrochloride medium has been studied. The mechanism of the extraction is proposed as follows: where (O) represents the organic phase, m=0,1,and logK0=4.23, logK1=8.67.

Key words: gold, extraction, trioctylamine
