摘要
选用N-乙烯基吡咯烷酮和间苯型不饱和聚酯为单体,合成了新型两亲性的超高交联吸附树脂(NU)。通过静态吸附实验,研究了NU树脂在不同温度下吸附水溶液中p-硝基苯酚的热力学和动力学特性,结果表明,吸附符合一级动力学方程,NU树脂吸附p-硝基苯酚符合Freundlich模型,通过计算△H<0,为放热反应。
New amphiphilic hypercrosslinked polymeric resins (NU) of isophthalie unsaturated polyester which was copolymerized with N-vinylpyrrolidone for removing p-nitrophenol from their aqueous solutions were prepared. The adsorption kinetics and thermodynamics of p-nitrophenol was carried out through static experiments. The results showed that the process of dynamics for the adsorption can be simulated by first order kinetic model. The adsorption date of p-nitrophenol onto the NU resin fit well into the Freundlich isotherm. AH was obtained and it is lower than zero, which indicated that the adsorption was exothermic reaction.
