▎ 摘 要
NOVELTY - Heavy metal ion adsorbing material comprises 50-60 pts. wt. cyclodextrin-cucurbituril-triazine based copolymer, 20-30 pts. wt. hyper-branched polyethyleneimine and 5-10 pts. wt. graphene oxide. USE - Used as heavy metal ion adsorbing material. ADVANTAGE - The material has low cost, heavy metal ion adsorption effect, large absorption capacity and easy absorption property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing heavy metal ion adsorbing material, comprising adding all raw materials to a screw extruder, blending and extruding at 230-250 degrees C, and molding to obtain final product.
