DOI: 10.11777/j.issn1000-3304.2015.14347, PP. 581-588

Abstract:
以无水氯化铁为氧化剂,采用化学氧化还原法合成了聚吲哚,利用静电纺丝技术制备了聚吲哚导电纳米纤维材料,研究了聚吲哚纳米纤维对重金属Cd2+的吸附行为.FTIR和NMR测试结果表明,化学氧化还原过程中吲哚的聚合是发生在吲哚单体的C2、C3位置.SEM和TEM观察表明,聚吲哚纳米纤维表面较光滑,呈圆柱状、没有珠节;纤维无规分布,平均直径约为145nm;聚吲哚纳米纤维的比表面积非常高,达73.45m2/g,其对重金属Cd2+具有良好的吸附能力,在pH=6时其对Cd2+平衡吸附量最大,约为140.36mg/g,平衡吸附时间约为50min.热力学分析表明聚吲哚纳米纤维对Cd2+的吸附行为用Freundlich模型描述更合理,动力学分析表明聚吲哚纳米纤维对Cd2+的吸附比较符合准二级动力学模型.再生10次后,其吸附量为100.67mg/g,是最大值的71%,是一种潜在的重金属Cd2+高效吸附材料.
