摘　　要：利用氯甲基化和亲核取代反应,制备了水杨酸型螯合树脂,并用FT-IR分析方法对其进行了检测。将所合成的树脂作为吸附材料,分别对Al^(3+)和Fe^(3+)溶液进行吸附实验,主要考察了吸附时间、温度及pH值等对树脂吸附性能的影响,得到了Al^(3+)和Fe^(3+)的最佳吸附条件。在Al^(3+)和Fe^(3+)最佳吸附条件下,改变吸附剂的质量,进行树脂对Al^(3+)和Fe^(3+)混合溶液的吸附实验。实验结果表明,这种树脂不仅可以同时吸附这2种离子,而且对这2种离子的吸附质量相差不大。By the chloromethylation and nucleophilic substitution reaction,salicylic acid type chelating resin was pre pared,and detected using FT-IR analysis method. The synthetic resin as adsorption material was carried on the adsorption experiments for AP＋ and Fe3＋ solution respectively,which mainly investigated the influences of the adsorption time, tern perature and pH value on chelation adsorption capacity for Al（ Ⅲ ） ion and Fe（ Ⅲ ） ion,got the best adsorption conditions of Al3＋and Fe3＋. In the best adsorption conditions of Al3＋ and Fe3- ,changing the quality of adsorbent, the adsorption experi ments of the mixed solution of Al3＋ and Fe3＋ were conducted. The experiments showed that this kind of resin not only can adsorb the two ions at the same time,but the distinction of the adsorption quality of the two ions was very small.
