摘　　要：研究了以蛭石作为吸附剂对汞的吸附作用 ,并探讨了蛭石的改性和添加絮凝剂的联合吸附情况。实验结果表明 ,蛭石对汞具有较强的吸附作用 ,吸附速度快 ;蛭石经 CTMAB改性后对汞的吸附能力显著提高 ;蛭石与絮凝剂之间存在协同作用 ,联合处理溶液中痕量汞的效果好 。The adsorption of vermiculite to mercury was studied,in addition the modification of vermiculite and joint adsorption with flocculant to mercury were inspected.Results showed that vermiculite had a stronger adsorption capacity to mercury and the adsorption process was quick.The adsorption capacity of vermiculite can be greatly in creased when modified with CTMAB.There existed a cooperation between vermiculite and flocculant when coping with trace mercury in solution,it was valuable to treat mercury wastewater with adsorption flocculant method.
