摘要
采用高能电子束辐射接枝技术,制备出新型离子交换纤维,并系统地研究了该离子交换纤维对金离子的吸附性能。实验结果表明,该新型离子交换纤维对金离子的吸附率达99.21%,吸附选择性较高,对环境的温度要求不高,常温可进行吸附作用,静态吸附服从Freundlich吸附等温式。该新型离子交换纤维在对工业废水中的贵金属回收再利用方面有很好的应用前景。
A new type of anion exchange fiber was prepared by high energy electron beam irradiation grafting technique.The adsorption performance of fiber on gold ions was systematically studied.The experimental results showed that the adsorption rate of gold ion by the fiber was 99.21%,the adsorption selectivity was high,and the adsorption process did not require high ambient temperature,and adsorption could be performed at normal temperature.The static adsorption was subjected to freundlich adsorption isotherm.The fiber had good application prospect in the recovery and reuse of precious metals in industrial wastewater.
