摘要
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。
The paper presents macroporous anion exchange resins with low exchanging capacity was synthesized by friedel-crafts crosslinking reaction and partial amination.Its exchanging capacity,selectivity for Au(I) and antiwear-tear ability were studied.Results showed that its capacity and selectivity for Au(I) as well antiwear-tear ability are obvious higher than that of general anion exhange resins and activated carbon
