摘　　要：通过配位聚合制备了一种新型的三元复合纳米材料(SC-GO-MPD)吸附剂,研究了吸附Cr^(6+)的性能,利用扫描电镜(SEM)及比表面积分析(BET)对吸附剂进行了表征分析。系统考查了吸附剂剂量,pH,初始Cr^(6+)浓度和共存阴离子对吸附性能的影响。结果表明:三元复合纳米材料形成了三维网状空间结构,且通过配位形式吸附Cr^(6+),在298 K下,吸附去除率最高可达99.31%,达到国标饮用水标准。The ternary composite nanomaterial(SC-GO-MPD)adsorbent was prepared by coordination polymerization,and the adsorption performance of Cr^(6+) was studied.The adsorbent was characterized by scanning electron microscopy and specific surface area analysis.The system examined the effects of adsorbent dosage,pH,initial Cr^(6+) concentration and coexisting anions on adsorption performance.The experimental results show that the ternary composite nanomaterials form a three-dimensional network structure and adsorb Cr^(6+) through coordination.At 298 K,the adsorption removal rate can reach 99.31%,reaching the national standard for drinking water.
