摘　　要：研究了用二甲胺和三甲胺的混合物作胺化剂,控制混合胺中各组成比例,使所制备的353E大孔双官能团阴离子交换树脂中2种官能团的比例适当。该树脂孔径适宜,分布均匀,总交换容量高,机械强度好,动力学性能好,适用于从氰化矿浆中提取金。353E macro-porous anion exchange resin having double functional groups, with appropriate ratio of two functional groups, was prepared by using bimethylamine and trimethylamine mixture as amination agent and controlling the various ratio of the mixed two amines in mixed amine. The resin with suitable and evenly distributed aperture has a high total exchange capacity, good mechanical strength and good dynamic performance. It can be used to extract gold from cyanidation pulp.
