为了处理电镀废水中的铜及镍,以棉纤维为原料,采用二乙烯三胺进行接枝共聚,制备了一种新型离子交换纤维.采用扫描电子显微镜、红外光谱仪对样品进行形貌及结构表征,并研究了不同时间、温度、pH条件下新型离子交换纤维对电镀废水中铜及镍的吸附效果.结果表明:该离子交换纤维中含有大量的氨基基团,在温度为35 ℃、pH为3~4,吸附时间为1 h时,对铜和镍有较好的吸附效果,且其饱和吸附量分别达到337.3 mg/g和396.9 mg/g,其吸附动力学符合准二级吸附速率方程,对铜和镍的吸附常数分别为2.8×10-5 g/(mg·min)和1.3×10-4 g/(mg·min). 研究为电镀废水中的铜及镍的安全处理提供理论依据.

To treat the copper and nickel in electroplating wastewater, we prepared a new ion exchange fiber by grafting copolymerization of diethylenetriamine using cotton fiber as raw materials. The morphology and structure of the samples were characterized by the scanning electron microscope and infrared spectrometer, and the absorption efficiencies of copper and nickel on ion exchange fiber in electroplating wastewater were studied at different times, temperatures and pH values. Result shows that the new ion exchange fiber contains a large number of amino groups, which has better adsorption efficiency to copper and nickel at 35 ℃, pH 3-4, the adsorption time of 1 h, and the saturated adsorption capacities of copper and nickel reach 337.3 mg/g and 396.9 mg/g, respectively. The adsorption kinetics of copper and nickel follow qseudo?鄄second order kinetics equations, the adsorption constant(K) of copper and nickel are 2.8×10-5 g/(mg·min) and 1.3×10-4 g/(mg·min), respectively. The study provides a theoretical basis for safe treatment of copper and nickel in electroplating wastewater.
