近年来,萃取原子吸收法测定微量金应用较普遍,但一般多采用盐酸介质以卤化金络阴离子形式进行萃取,因而大量铁严重干扰测定。此外据文献介绍,用高分子胺萃取金大致有:三辛胺二异丁基酮,含有季胺盐的二丁异丁基酮及三辛胺-氯仿等,这些方法虽快速, In recent years, extraction of atomic absorption spectrometry for the determination of trace gold is more common, but more commonly used hydrochloric acid medium to extract the form of halogenated gold anions, and thus a lot of iron seriously interfere with the determination. In addition, according to the literature, the extraction of gold with polymer amines are generally: trioctyl amine diisobutyl ketone, quaternary ammonium salt containing dibutyl isobutyl ketone and trioctylamine - chloroform, etc. Although these methods are fast,
