摘　　要：为了研究不同种类的海藻酸纤维对铜离子的吸附性能,用盐酸及硫酸钠水溶液处理海藻酸钙纤维,分别得到海藻酸及海藻酸钙钠纤维。把三种纤维分别与含铜离子的水溶液接触后,在不同的时间段测试溶液中铜离子的浓度。结果显示:海藻酸、海藻酸钙及海藻酸钙钠纤维对铜离子均有较好的吸附性能,其平衡吸附容量分别为68.6mg/g、81.7mg/g和71.0mg/g,海藻酸钙纤维的吸附容量在三种纤维中最高;由于海藻酸钙钠纤维遇水后可以很快地吸水膨胀,其吸附速度较其它两种纤维快。In order to study the adsorption of copper aqueous HC1 and Na2SO4 solutions to treat calcium sodium alginate fiber respectively. The three types ions by various types of alginate fibers, this paper used alginate fibers to make alginic acid fiber and calcium of fibers were placed in aqueous solutions containing copper ions and the ion concentrations were measured at different periods of time. Results showed that the equilibrium adsorption capacities for copper ions were 68.6 rag/g, 81.7 mg/g and 71.0 mg/g respectively for alginic acid, calcium alginate and calcimn sodium alginate fibers, with calcium alginate fiber having the highest adsorption capacity. Because it could swell rapidly in water, the adsorption speed was highest for the calcium sodium alginate fiber.
