▎ 摘　　要

NOVELTY - Preparation of ion separation membrane comprises dissolving mixture of graphene oxide and polyvinylidene fluoride in N-methyl pyrrolidone solution to obtain pre mixed emulsion, soaking emulsion coated plates and adsorbents in mixture of ethanol and water, scraping and drying. The mass ratio of graphene oxide, polyvinylidene fluoride and N- methyl pyrrolidone was 1:20:100. USE - The method is for preparation of ion separation membrane. ADVANTAGE - The method has high specific recognition ability and adsorption and separation ability for rubidium ion.
