摘要
基于壳聚糖(CS)与聚甲基丙烯酸(PMAA)间的复合作用制备了CS与PMAA的聚电解质复合型水凝胶.利用荧光光谱研究CS与PMAA的相互作用,结果表明随介质环境pH值的变化,凝胶中PMAA的构象在压缩线团和伸展态之间变化,该凝胶具有溶解和释放稠环芳烃的能力,可望在稠环芳烃污水处理上获得应用.
A complex gel of CS and PMAA was prepared as a result of the coordination reactions between CS and PMAA. It shows, by the study of interaction between CS and PMAA using fluorospectrmetry, that PMAA conformation in the gel changes between compact state and loose state with the change of pH in the medium , resulting in the function that gel dissolves or releases multinuclear aromatics. It is expected that this technology may be used in the treatment of waste water containing multinuclear aromatics.
