Abstract

In this study, FeO/chitosan/polypyrrole (FeO/CS/PPy) magnetic adsorbents were successfully synthesized using the chemical oxidation polymerization method. These adsorbents were characterized by SEM, FT-IR, TGA, and XPS. The results of batch adsorption experiments showed that the FeO/CS/PPy composite exhibited a maximum adsorption capacity of 193.23 mg g in a 100 mg L Cr(vi) solution at 298 K, with a pH of 2.0. The adsorption behavior of the adsorbent to Cr(vi) was in good agreement with the Langmuir isothermal model and the quasi-second-order kinetic model. Thermodynamic studies indicated that the process of adsorption was spontaneous and endothermic. The mechanism of adsorption may be attributed to electrostatic interactions and chemical reduction. After five cycles, the removal efficiency of the FeO/CS/PPy composite for Cr(vi) has consistently remained at 84.32%. Overall, the FeO/CS/PPy composite exhibits great potential as an adsorbent for effectively removing Cr(vi) from aqueous solutions.

摘要

在本研究中，采用化学氧化聚合法成功合成了FeO/壳聚糖/聚吡咯（FeO/CS/PPy）磁性吸附剂。通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）、热重分析（TGA）和X射线光电子能谱（XPS）对这些吸附剂进行了表征。批量吸附实验结果表明，在298K、pH值为2.0的100mg/L Cr(VI)溶液中，FeO/CS/PPy复合材料表现出的最大吸附容量为193.23mg/g。吸附剂对Cr(VI)的吸附行为与朗缪尔等温模型和准二级动力学模型吻合良好。热力学研究表明，吸附过程是自发的且吸热的。吸附机制可能归因于静电相互作用和化学还原。经过五个循环后，FeO/CS/PPy复合材料对Cr(VI)的去除效率一直保持在84.32%。总体而言，FeO/CS/PPy复合材料作为一种从水溶液中有效去除Cr(VI)的吸附剂具有巨大潜力。
