摘　　要：合成了一种用咪唑烷修饰的超高交联吸附树脂LG-01,并用二甲氨基修饰的超高交联吸附树脂NDA99作对照,比较了它们对水溶液中2-咪唑烷酮的静态吸附和脱附行为。结果表明,经过咪唑烷修饰的吸附树脂LG-01在一定温度时对2-咪唑烷酮的吸附过程中存在不可逆吸附作用和氢键作用,LG-01对2-咪唑烷酮的吸附能力明显强于NDA99,2种树脂对2-咪唑烷酮的吸附均符合Langmuir方程和Freundlich方程。The resin （named LG-01） modified with imidazole during the post-crossing of chloromethyl low crosslinking macroporous poly-styrene resin was prepared. The adsorption performance of 2-imidazolidone onto LG-01 was studied through static adsorption and desorption experiment, and the commercial resin NDA99 modified by dimethylamine was used as a reference. The results show that because of the obviously irreversible adsorption and hydrogen bonding interaction during the adsorption process, LG-01 has a good adsorption capability to 2- imidazolidone. The adsorption isotherms of 2-imidazolidone with LG-01 and NDA99 resins can be fitted with Langmuir and Freundlich equation.
