摘　　要：研究了二丁基卡必醇（ＤＢＣ）萃淋树脂吸萃金的机理，溶液酸效应、吸附等温线、吸附速炫、盐析剂应柱操作条件等，将该树脂用于矿样中金含是珠测定，结果与７１７离子交换树脂吸附法一致。Adsorption properties and mechanism of gold were studied under different conditions. The results showed that dibutyl carbitol (DBC) levextrel resin is a new selective stationary phase for gold. It was found that gold can be retained on DBC resin column in 1. 0 mol/L HC1. The eluant of gold is 2% thiorea solution. The recovery of gold in the determination of ore sampies is almost the same as the adsorption by 717# resin.
