摘要

通过水热反应法制备了TiO₂,再采用化学方法制备了不同TiO₂含量的聚苯胺(PANI)复合材料,运用扫描电子显微镜(SEM)和紫外-可见光光谱仪(UV-Vis)等手段对其形貌和结构进行表征;研究了聚苯胺复合材料吸附甲基橙的性能及其动力学过程,并探讨了TiO₂含量、吸附时间、吸附剂质量等因素对其吸附性能的影响。结果表明:TiO₂、PANI和PANI/TiO₂复合材料形貌均为颗粒状;PANI/TiO₂复合材料对甲基橙的吸附率比纯PANI吸附率较高,TiO₂含量为8%的PANI复合材料对甲基橙的吸附率较高;随着吸附剂质量的增加,PANI/TiO₂复合材料对甲基橙的吸附率呈现不断增大趋势,当PANI/TiO₂质量不大于0.033g时,其吸附率增加较快;对吸附过程通过动力学准一级和准二级方程拟合可知,PANI/TiO₂复合材料吸附甲基橙过程符合准二级动力学方程。

Abstract

TiO₂ was prepared through the hydrothermal synthesis,and polyaniline (PANI)/TiO₂ composites were synthesized by the chemical method.The morphology and structure of PANI/TiO₂ were characterized by scanning electron microscope (SEM) and ultraviolet visible light spectrometer (UV-Vis).The adsorption performance and the kinetic of PANI/TiO₂ composites as the adsorbent for the removal of the methyl orange (MO) was studied,and investigated the effects such as the content of TiO₂,adsorption time,the mass of the adsorbent on the adsorption performance of the composite.The results were as follow: the morphologies of TiO₂,PANI and PANI/TiO₂ were granular with the different diameter.In terms of adsorption perspective,the adsorption ratio of PANI/TiO₂ was higher than that of pure PANI.The adsorption ratio increased with the amount of the adsorbent increasing,the adsorption ratio of PANI/TiO₂ markedly increased when the weight was not higher than 0.033g.The adsorption kinetics of PANI/TiO₂ composites was the quasi-second-order kinetic equation,according to the quasi-first-order and quasi-second-order kinetic equations.
