摘　　要：为了消除染料对环境的污染,使用4种酸、膨胀石墨(GIC)为掺杂剂,过硫酸铵为氧化剂,采用原位聚合法制备了聚苯胺/膨胀石墨复合材料吸附剂。利用紫外、SEM等手段对材料进行表征。结果表明,成功制备具有纳米棒状结构材料。使用聚苯胺/膨胀石墨复合材料进行吸附实验,研究了吸附剂质量、温度、pH等因素对吸附条件的影响。吸附实验表明对染料的去除率达到95%以上。吸附动力学曲线表明吸附过程符合准二级动力学,以化学吸附为主。In order to eliminate the environmental pollution caused by dyes,the adsorbent of polyaniline/expanded graphite composite was prepared by in-situ polymerization using four kinds of acids,expanded graphite(GIC)as dopant and ammonium persulfate as oxidant.The materials were characterized by UV and SEM.The results showed that the material was successfully prepared and had a nanorod-like structure.The adsorption experiments of polyaniline/expanded graphite composites were carried out to study the effects of adsorbent quality,temperature,pH value and other factors on the adsorption conditions.The adsorption experiment showed that the removal rate of dye was over 95%.The adsorption kinetic curves indicated that the adsorption process was consistent with quasi-secondary kinetics and is dominated by chemisorption.
