摘要:
对膨润土-丙烯酸钠聚合机理、聚合产物吸水特征、Cu2+ 吸附及解吸特征进行了研究,研究结果表明: 丙烯酸钠聚合反应主要发生在颗粒间,还有少量丙烯酸钠在蒙脱石层间发生聚合反应;适量膨润土的添加会改善聚合物的吸水性能;较高浓度Cu2+ 溶液中,膨润土的添加对其吸附性能无显著影响,但会减缓聚合物解吸速度;聚合物吸水过程符合伪一级动力学方程;离子吸附及解吸过程符合伪二级动力学方程.
Abstract:
The mechanism of copolymerization of bentonite-acylic acid sodium and the characteristics of water absorption,Cu2+adsorption and desorption were investigated. Acrylic acid mainly reacts around bentonite particles, and still a few of acylic acid reacts in the interlamination of montmorillonite. The addition of bentonite can improve the water- absorption property of the copolymer within a certain addition amount range. In high concentration of Cu2+solution,the addition of bentonite produse no significant effect on the Cu2+adsorption property of the copolymer, but it will retard the Cu2+ desorption process. The water-absorption process of the copolymer follows pseudo first order kinetics equation, and the ion adsorption and desorption process follows pseudo second order kinetics equation.
