摘要
本文描述了一种新型吸附树脂的合成和应用。作者以氯甲基化苯乙烯—二乙烯苯共聚体为原料,经傅氏催化剂作用,使其发生自身的傅氏交联反应;并研究了催化剂用量、反应温度和时间等对此反应的影响;确定了最佳反应条件,从而制得了一种高比表面(1200～1400m^2/g)的新型吸附树脂。新树脂应用于纯苯酚水溶液的吸附和脱附,实验结果表明其吸附性能和脱附效率优良。
The synthesis and application of a new polymeric adsorbent are described in this paper. The author has studied the Fridel-Crafts crosslinking reaction of the chloromethylated copolymer of styrene-divinylbenzene by itself in the different reaction conditions, such as, amount of catalyst, reaction temperature and length of reaction time, etc. Thus, the optimal reaction condition is determined, and a new polymeric adsorbent of high specific surface area (1200-1400 m2/g) is obtained. Results from static state and column experiments of the new adsorbent for adsorbing phenol in water have shown its adsorption capacity and the desorption efficiency are excellent.
