| 摘 要： | 研究了聚乙烯基吡啶改性硅胶(PVP/SiO2)、聚苯乙烯改性硅胶(PS/SiO2)、胺化聚苯乙烯改性硅胶(PS-NH2/SiO2)等3种有机-无机复合材料吸附剂对苯胺的吸附行为。吸附动力学研究表明,3种吸附剂对苯胺的吸附均符合准二级动力学方程。对其粒内扩散模型模拟的结果表明,在3种吸附过程中液膜扩散为主要速率控制步骤。用Langmuir等温吸附方程式和Freundlich等温吸附方程式对其吸附等温线进行了拟合,结果表明,PVP/SiO2、PS/SiO2对苯胺的吸附符合Freundlich等温吸附方程式。

| Abstract: | The adsorption behaviors of aniline on three Inorganic-organic complex materials poly(4-vinylpyridine)-modified silica(PVP/SiO2),polystyrene-modified silica(PS/SiO2) and ammoniated polystyrene-modified silica(PS-NH2/SiO2) were studied.Results of kinetics indicated that all the adsorption processes of the three adsorbents toward aniline were governed by the film diffusion and followed pseudo second-order reaction.Researches of thermodynamics showed that the processes of adsorption of aniline on PVP/SiO2 and ... |
