摘　　要：合成了一种用乙酰苯胺修饰的新型超高交联吸附树脂ZH-05,并用Amberlite XAD-4作对照,比较了它们对水溶液中对甲苯胺的静态吸附和脱附行为。结果表明:经过乙酰苯胺修饰的吸附树脂ZH-05在一定温度下对对甲苯胺的吸附过程中存在化学吸附,ZH-05对对甲苯胺的吸附能力明显强于AmberliteXAD-4,两种树脂对甲苯胺的吸附均符合Freundlich方程。Compared with Amberlite XAD-4, new polymeric adsorbent modified with acetylaniline （ZH-05） was prepared and used for adsorbing 4-methylaniline in aqueous solution, including the static equilibrium adsorption and desorption characteristics at different temperature, and the adsorption mechanism was further investigated. The result shows that chemical interaction will be in existence in the adsorption process of 4-methylaniline in aqueous solutions with ZH-05 at the right temperature and the adsorption capacities of 4-methylaniline in aqueous solutions with ZH-05 is obvious much higher than that of Amberlite XAD-4. All the adsorption data at different temperature are fit for Freundlich equation perfectly.
