摘要
在静态条件下,研究了水溶液中超高交联树脂ZZ和大孔吸附树脂Am berlite XAD-4吸附2-甲基-4-氯苯氧乙酸的热力学特性,测定了283K和323K温度下的吸附等温线。对两个温度下的吸附等温线的比较和热力学数据的计算,结果表明,在稀溶液中两种吸附剂对2-甲基-4-氯苯氧乙酸的吸附同时符合Langm u ir和F reund lich模型,并且两种吸附剂对2-甲基-4-氯苯氧乙酸的吸附都是放热过程。
Under the static conditions ,the thermodynamics properties about adsorpting agritox in aqueous solution have been studied with the newly hyper -- cross linked resins ZZ synthesized by ourselves and macroporous adsorbent Amberlite XAD--4, including of the adsorption isotherms at 288K and 303K temperature. By the thermodynamics functional values and the adsorption isotherms at 288K and 303K temperatures ,the results show that the adsorptions for agritox in aqueous solution on the two adsorbents are both fit for Langmuir and Freundlich equations, and the adsorptions for aniline and 4-nitroaniline on ZZ and XAD-4 proved to be an exothermic process.
