Abstract

Abstract: The structure and morphology of palygorskite/poly(ethylene glycol)/acrylic acid (PGS/PEG/AA) hydrogel produced by glow discharge electrolysis plasma were characterized by FT-IR,XRD and SEM. The adsorption behaviors of hydrogel for cationic dyes,such as methylene blue,crystal violet,Malachite green and Rhodamine B,were investigated. Factors influencing the adsorption of cationic dyes,such as solution pH,contact time,were investigated. In addition,the adsorption mechanism was also discussed. The results showed that PEG and AA had successfully grafted to PGS. The hydrogel possessed a better interface compatibility and exhibited undulant,rough and porous surface. The best parameters for the removal of dyes were pH 6.2 and the equilibrium contact time 3h. The adsorption process followed a pseudo-second-order kinetic model. The dyes adsorption on PGS/PEG/AA hydrogel was a complex physical-chemical process due to ion-exchange,hydrogen bonding and van der Waals.

Key words: palygorskite, hydrogel, adsorption, cationic dyes

摘要： 采用红外光谱、X射线衍射和扫描电镜对辉光放电电解等离子体引发制备的坡缕石/聚乙二醇/丙烯酸(PGS/PEG/AA)水凝胶的结构和形貌进行了表征.研究了其对阳离子型染料亚甲基蓝、结晶紫、孔雀石绿和罗丹明B的吸附行为,考察了pH值、吸附时间对吸附性能的影响,同时探讨了可能的吸附机理.结果表明,PGS、PEG和AA发生接枝共聚形成水凝胶,组分间相容性好,表面呈现褶皱和深浅不均匀的孔洞;吸附的最佳pH值为6.2左右,吸附时间为3h,吸附动力学符合准二级模型,阳离子染料在PGS/PEG/AA上的吸附是由离子交换、氢键、范德华力等共同作用的物理化学过程.
