| 摘 要： | 采用静态吸附试验方法——聚丙烯腈基羧酸型阳离子交换纤维对水溶液中的铜离子(Cu2+)进行吸附.研究溶液浓度、pH值、温度等因素对吸附量的影响,对吸附动力学和再生性能进行了分析.结果表明,离子交换纤维对Cu2+吸附20 min就达到吸附平衡,吸附量受溶液浓度和溶液pH值影响较大,浓度越高平衡吸附量越大,pH值接近6时吸附量高,并且吸附量受温度的影响较小.纤维对Cu2+的静态吸附量达到2.1 mmol/g,在吸附前后变化不大,性质稳定,可以循环使用。

| Abstract: | Static adsorption method was used to study the adsorption behavior for Cu2+ of weak acid cation exchange fiber.Influence of concentration of Cu2+,pH value and temperature were studied.Adsorption rate and regeneration of the fiber were also investigated.Results show that the fiber reaches adsorption equilibrium in 20 min,and the adsorption capacity increases along with the concentration of Cu2+ and pH value.The adsorption capacity reached the maximum,which was 2.1 mmol/g,when pH value near 6.The influence of... |
