摘　　要：利用表面负载的方法将有机化磁性凹土与苯乙烯、二乙烯苯等制备磁性凹土树脂;对磁性凹土树脂进行氯甲基化改性,制备出氯化磁性凹土树脂。表征了样品的形貌、结构以及表面积,研究了树脂对天然有机物(腐殖酸)的吸附性能。结果表明:氯化后的磁性凹土树脂的比表面积是原有的1.9倍,对附腐殖酸的饱和吸附能力也从原有的41.84 mg/g提高到了51.02 mg/g,这表明改性后的树脂增强了其对腐殖酸的去除能力。The magnetic attapulgite resin（Resin） was prepared by the method of surface loading,with the organic magnetic attapulgite（Fe3O4-ATP）,styrene and divinylbenzene. Then,magnetic concave soil resin to make use of chlorine methyl functional modification,preparation of chlorinated magnetic attapulgite resin（Resin-Cl）. The morphology,structure and surface area of Resin-Cl were characterized. The adsorption properties of Resin-Cl on natural organic matter（humic acid） were studied.Results show that：The specific surface area of the chlorinated magnetic attapulgite resin is 1. 9 times that of the original. And the saturated adsorption capacity of humic acid was also increased from the original 41. 84 mg/g to 51. 02 mg/g. This shows that the modified resin to enhance its ability to remove humic acid.
