摘要

本文采用双脉冲一步共沉积法制备了ZSM-5/聚苯胺/聚苯乙烯磺酸钠(ZSM-5/PANI/PSS)电活性膜,通过FT-IR、XRD和SEM对ZSM-5/PANI/PSS电活性膜进行了表征. 由水热法合成纳米级ZSM-5颗粒,经超声处理将ZSM-5分散,有利于合成均匀的ZSM-5/PANI/PSS电活性膜. 实验结果表明该电活性膜对Pb2+具有优良的选择分离性能,在10 mg﹒L-1的Pb2+溶液中电控离子交换法对Pb2+的去除率是传统离子交换法的2.3倍,且前者的平衡吸附量是后者的2.5倍. 吸附过程满足Langmuir等温吸附方程,ZSM-5/PANI/PSS电活性膜对Pb2+的交换量高达235 mg·g-1. 吸附过程为准一级动力学吸附,电控离子交换过程的准一级吸附速率常数(0.0227 g·mg-1·min-1)明显高于传统离子交换(0.0117 g·mg-1·min-1). 该电活性膜在电控离子交换处理废水领域具有很好的应用前景.

Abstract

A novel electroactive composite film consisting of ZSM-5/polyaniline/polystyrene sulfonate(ZSM-5/PANI/PSS) was prepared by double pulse one step co-deposition method. The ZSM-5/PANI/PSS composite film was characterized by FT-IR, SEM, XRD, and XPS techniques. The highly crystalline nano-ZSM-5 was synthesized by hydrothermal method, which could be evenly dispersed in aqueous solution by ultrasonic treatment. The synthesis condition of composite film was optimized through changing the pH value of solution. The ZSM-5/PANI/PSS composite film showed higher adsorption capacity for Pb2+ ions. Langmuir model was applied to analyze the adsorption process. The adsorption capacity of composite film for Pb2+ ions was 235 mg·g-1. The adsorption kinetics of Pb2+ ions could be described properly by the pseudo-first-order kinetic mode.Furthermore, the pseudo-first-order rate constant was determined to be 0.0227 g·mg-1·min-1 in ESIX process, which is higher than that of 0.0117 g·mg-1·min-1 in IX process. Therefore, the ZSM-5/PANI/PSS composite film is expected to be a promising material in the field of waste treatment.
