摘　　要：本文系统地研究了用辐射引发苯乙烯—二乙烯基苯与聚乙烯醇无纺布接枝共聚并进一步磺化制得的强酸型阳离子交换纤维SPVA—g—PSt—DVB与过渡和稀土金属离子交换吸附的基本性能。并且探讨了用这种纤维富集稀土离子矿浸出液的可能性。In this paper the base characteristics of ion exchange and adsorption of strong acidic cational exchange fiber, which has been obtained by radiation induced graft copolymerization of styrene - divinyl bezene onto polyvinyl alcohol non-woven fabric, followed by sulfona-tion, towards transition and rare earth metal ions have been studied. It has also been inquired into the possibility of concentration of the dilute extracted solution of ionic rare earth ore.
