氯化磁性凹土树脂的制备与表征研究

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.

Preparation and Characterization of Chlorinated Magnetic Attapulgite Resin

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.
