▎ 摘  要

NOVELTY - A heavy metal ion absorption composite membrane comprises graphene oxide, aminotriazole, 4-chloromethylstyrene, initiator and ion exchanger. USE - Heavy metal ion absorption composite membrane. ADVANTAGE - The product has good practical application and high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of heavy metal ion absorption composite membrane comprising: (A) adding aminotriazole with graphene oxide solution of ethanol, ultrasonically processing for 5-10 minutes, reflux reacting at 80-100 degrees C for 48-60 hours, removing upper layer clear liquid, water washing to neutral, and drying into vacuum drying box at 60-80 degrees C for 12-24 hours to prepare aminotriazole embellished graphene oxide; (B) dissolving into anhydrous tetrahydrofuran under nitrogen atmosphere, gradually adding 4-chloromethylstyrene, reacting under nitrogen atmosphere at 50 degrees c for 4-8 hours, water washing to neutral, and drying into vacuum drying box at 40 degrees C for 24 hours to prepare composite graphene oxide polymerizable ionic liquid composite monomer; and (C) mixing with initiator, heating under inert gas for 1-3 hours, sedimenting, washing, drying into vacuum drying box to 60-80 degrees c for 6-10 hours, dissolving into organic solvent to prepare 2-5% polymer-containing solution, dropping on PTFE board, drying to 80 degrees C for 10-20 hours to prepare polymer composite membrane, leaching using 0.2-1 M ion exchanger water solution for 36-72 hours, and drying into vacuum drying box to 60-80 degrees C for 15-24 hours.
