摘要

采用聚乙烯醇(PVA)、聚丙烯酰胺(PAM)为原料，戊二醛(glutaraldehyde)为交联剂，制备了一种互穿网络(IPN)水凝胶。用傅立叶红外光谱仪对其结构进行表征，研究了PVA和PAM按不同配比及交联剂的不同用量制备的IPN水凝胶的吸水性和Cu²⁺的吸附性，主要探讨了吸附时间、pH、吸附温度等对吸附Cu²⁺的影响，分析了吸附行为及其动力学特性，并对其吸附机理做出了初步探讨。结果表明：在本实验研究范围内，30wt.% PAM含量的PVA-PAM IPN水凝胶在pH=5时对Cu²⁺的吸附效果最佳；在一定温度范围内，PVA-PAM IPN水凝胶对Cu²⁺的平衡吸附量随温度升高而增大；吸附行为符合准一级和准二级动力学方程，扩散机制为颗粒内扩散和膜扩散双重作用。

Abstract:

An interpenetrating polymer network (IPN) hydrogel was prepared by using polyvinyl alcohol (PVA), polyacrylamide (PAM) as raw materials and glutaraldehyde as cross-linking agent. The structure of the IPN was characterized by Fourier transform infrared spectroscopy. The effect of PAM content, the amount of cross-linking agent, adsorption time, pH and adsorption temperature on swelling degree and Cu²⁺ adsorption properties of IPN hydrogel were studied. The Cu²⁺ adsorption kinetic characteristics of the IPN and the adsorption mechanism were investigated. The results showed that the 30wt.% PAM IPN had better Cu²⁺ adsorption property than PVA hydrogel when the pH was 5. The equilibrium adsorption amount of Cu²⁺ on PVA-PAM IPN hydrogel increased with the increase of temperature. The adsorption behavior was consistent with the pseudo-first-order and pseudo-second-order kinetic equations, and the mechanism diffusion was controlled by particle and film diffusions.

Key words: interpenetrating polymer networks hydrogel adsorption kinetics adsorption mechanism
