摘要

以聚四氟乙烯纤维为基体通过60Co辐射引发与丙烯酸接枝制备弱酸性阳离子交换纤维 .产物功能基含量为 3.06mmol/g

在pH=5时该纤维达到对Cu2+ 的最大动态吸附量为107.48mg/g.使用不同浓度HCl对饱和吸附铜的接枝纤维进行洗脱

证实该纤维对铜离子具有优异的解吸性能.

Abstract

Abstract A novel cation exchanger fiber w“prepared by irradiating grafting of acrylic acid at the surface of FE fibers The novel cation exchanger fiber not only has the advantages as a commercial cation exchanger fiber

but also has good corrosion resistance．It was found that the pH titration curve of the grafted mE fibet showed a sudden jump from pH=6 to 10

which was different from the behavior of a typical commercial weakly acid exchanger．This hovel g fted PTFE fibet was used to remove Cu“at different pH conditions．11le best pH value for the Cu“adsorption ale at 3～5．The highest adsorption capacity for Cu“is 107．48 mg／g．when the pH value is 5．The Cu“ ions eai'l be desorbed completely by dilute HCl solutions
