【摘要】 应用化学涂敷法制备了铜离子螯合纤维,考察了其对铜离子的平衡吸附过程及pH值对吸附性能的影响,对比了螯合纤维及D113树脂吸附铜离子的速率,并用准一级和准二级动力学方程对实验数据进行分析拟合,从而得出结论——在相同的pH值和浓度下,螯合纤维的吸附速率是D113树脂吸附速率的十几倍。更多还原

【Abstract】 A kind of ion chelating fiber was prepared by gel-coating method. The equilibrium sorption for was studied and effect of pH on sorption capacity was discussed. Sorption rate for Cu2+ of the chelating fiber and D113 resin was compared and experimental data was analyzed with the pseudo first-and pseudo second-order equations. The conclusion was that at the same pH and concentration,the chelating fiber possessed many times higher sorption rate as compared to commercial D113 resin.更多还原
