采用Ｆｒｉｅｄｅｌ－Ｃｒａｆｔｓ交联和部分胺化反应合成了一种低交换容量的大孔阴离子交换树脂，研究其对氰化液中Ａｕ（Ｉ）的交换能力。结果显示，该树脂对Ａｕ（Ｉ）的交换量，选择性和在矿浆中的耐磨损性明显高于普通阴树脂和活性炭。
A kind of macroporous anion exchange resin with low exchange capacity was synthesized by Friedel-Crafts cross-linking and partial amination reaction. The exchange capacity of Au (I) in cyanide solution was studied. The results showed that the exchange capacity, selectivity and wear resistance of the resin to Au (I) were obviously higher than those of ordinary anion resin and activated carbon.
