▎ 摘　　要

NOVELTY - Preparation of ceramic composite membrane comprises subjecting graphite raw material into full intercalation oxidation to prepare graphene oxide and graphene oxide solution; applying graphene oxide solution to surface of microporous ceramic filter membrane to form thin layer of graphene oxide film; and subjecting ceramic filter membrane into chemical reduction at high temperature and under inert atmosphere. USE - Preparation of ceramic composite membrane used for seawater desalination or sewage treatment. ADVANTAGE - The method produces ceramic composite membrane with long service life, has improved filtration separation effect, has simple preparation, and suitable for industrial production.
