以苯乙烯为聚合单体，二乙烯基苯为共聚单体，采用悬浮聚合法制备苯乙烯一二乙烯基苯共聚珠体，然后用浓硫酸磺化制得阳离子交换树脂。傅立叶变换红外光谱（FTIR）分析表明，成功制备了阳离子交换树脂。试验用NaOH标准溶液滴定浸泡过离子交换树脂的NaCl溶液的方法测定交换容量的大小为4．50mmol／g。以宁夏固原市自来水为研究对象，用制备的苯乙烯型阳离子交换树脂对其进行软化，采用EDTA（乙二胺四乙酸二钠盐）滴定法测量自来水浸泡阳离子交换树脂前后硬度的变化，结果表明，制备的离子交换树脂交换性能良好，降低了固原市自来水的硬度。

The eopolymer beads body of the styrene and divinyl benzene is prepared by the suspension polymerization of styrene as the polymerizable monomer and divinyl benzene as a comonomer, and then is sulfonated into the cation exchange resin by the concentrated sulfuric acid. F-FIR indicated that the cation exchange resin has been made successfully. Test meth- od that a NaOH standard solution titrated the NaC1 solution in ion exchange resin is made to determinate the size of the exchange capacity, which is 4.50(mmol/g). Guyuan City tap water as the research object is softened by the prepared cation exchange resin of styrene-type. EDTA ( ethylenediamine tetraacetic acid disodium salt) titration method is used to measure the tap water change in hardness before and after cation exchange resin is soaked. The results showed that the prepared ion- exchange resin have a good exchange performance and greatly reduced hardness of Guyuan City tap water.
