磁性离子交换树脂（如MIEX等）能有效去除大部分溶解性有机物(DOC)及溴离子等，减少消毒副产物(DBPs)的生成，为生产安全优质的饮用水提供新途径。而m-PGMA是一种新型的自主研发的磁性离子交换树脂材料。阐述了m-PGMA的基本特性，并利用烧杯试验，研究了其对原水中痕量有机物的去除效能，并与MIEX进行了对比试验。以原水中卡马西平、磺胺嘧啶、阿特拉津为目标痕量有机物，通过高效液相色谱法等方法进行测定。结果表明：m-PGMA对于磺胺嘧啶有明显的去除效果，在反应时间为60 min，投加量为12 mL/L时，去除率达到83%；其对卡马西平及阿特拉津的去除效果则较为低下，在反应时间为60 min，投加量为12 mL/L时，卡马西平去除率一般只有24%，阿特拉津去除率则一般不超过15%。

Magnetic ion exchange resin (MIEX) can effectively remove most of the dissolved organic matter (DOC) and bromide ions, which is able to reduce disinfection byproducts (DBPs), definitely providing new method for safe and high quality drinking water. The magnetic ion-exchange resin called m-PGMA is an independently developed new resin material. This paper describes the main characteristics of m-PGMA. Moreover, by using beaker experiment, a study of its trace organics removal performance in raw water has been done as well as a comparison with MIEX. In raw water, carbamazepine, sulfadiazine, atrazine were set as target trace organics. A high performance liquid chromatography and other equipment were used to estimate the removal effect. The results showed that, due to m-PGMA nearly 83% of sulfadiazine was removed with a dosage of 12 mL/L at a contact time of 60 min;while removal efficiency of both carbamazepine and atrazine were relatively low. At a contact time of 60 min, with a dosage of 12 mL/L, the removal rate didn't exceed 24% of carbamazepine, while atrazine removal rate was never above 15%.
