摘    要:比较了2种超高交联聚苯乙烯吸附树脂NDa99与ZH-04对甲苯的静态吸附行为.结果表明,在288~293 K和研究的浓度范围内,ZH-04、NDa99对甲苯的吸附平衡数据符合Freundlich和Langmuir吸附等温方程.吸附为放热过程,适当降低温度有利于吸附,并计算了甲苯在ZH-04和NDa99树脂上的吸附焓变、自由能变和熵变,对吸附行为进行了合理的解释,为废水处理提供一定的理论依据.

关 键 词:超高交联吸附树脂  吸附热力学  甲苯

Abstract:A comparison of adsorption properties of the hypercrosslinked polymeric resins ZH-04 And NDa99 for the toluene was made,including the static equilibrium adsorption isotherms and the adsorption thermodynamic properties.Within temperature range of 288~293 K and investigative concentration range,equilibrium data for the adsorption of toluene from aqueous solutions by ZH-04 And NDa99 adsorbents had been obtained and were correlated with Freundlich and Langmuir equation.The results showed that the process of adsaorption of toluene from aqueous solution by ZH-04 And NDa99 is an exothermic process.Estimations of the isosteric enthalpy change of adsorption,free energy change and entropy change of adsorption are reported,and the adsorption behaviors are reasonable interpreted.Result of macroporous resins in the removal of toluene in aqueous solution is helpful to the further research of wasterwater application.
Keywords:hypercrosslinked polymeric resin  adsorption thermodynamics  toluene
