1、山东科技大学本科毕业论文摘要复合高吸水性树脂(SuperabsorbentComposite)是一种新型功能高分子材料。它具有吸收比自身重几百到几千倍水的高吸水功能，并且保水性能优良，一旦吸水膨胀成为水凝胶时，即使加压也很难把水分离出来。因此，它在个人卫生用品、工农业生产、土木建筑等各个领域都有广泛用途。本文研究了CTS-g-P(AA-co-AM)/KL复合高吸水性树脂对甲基紫的吸附特性，考察了吸附时间,甲基紫的初浓度，pH，离子强度对吸附量的影响。结果表明随着吸附时间的延长，树脂对甲基紫的吸附量增加，24后，吸附作用基本达到平衡；吸附量随甲基紫初浓度的增大而增大；吸附量随pH
2、增大先增加，当pH=4时达最大，此后，pH增大，吸附量下降；随着离子浓度的增加，吸附量呈下降趋势。CTS-g-P(AA-co-AM)/KL高吸水性树脂对甲基紫有很好的吸附作用，室温最大吸附量为1500mg/g，在印染废水处理过程中具有一定的应用价值。关键词复合高吸水性树脂；甲基紫；吸附IV山东科技大学本科毕业论文AbstractSuper Absorbent Polymer，SAPisanewtypeoffunctionalpolymermaterials.Ithassuckedreceivedmorethanafewhundredtoathousandtimesitsownw
