▎ 摘　　要

NOVELTY - Constructing organic-inorganic composite material useful for synchronously removing hexavalent chromium ion and phenol method, comprises (i) preparing conjugated polymer 1,4-diphenyldiacetylene; (ii) preparing graphene oxide; (iii) constructing binary composite material graphene oxide/1,4-diphenylbutadiyne; (iv) constructing ternary organic inorganic composite material aurum-graphene oxide/1, 4-diphenyldiacetylene; and (v) placing the ternary organic-inorganic composite material aurum-graphene oxide/1, 4-diphenyldiacetylene into waste water containing hexavalent chromium ions and phenol, simultaneously, removing hexavalent chromium ions and phenol by visible light irradiation. USE - The organic-inorganic composite material construction is useful for synchronously removing hexavalent chromium ion and phenol (claimed). ADVANTAGE - The composite material has high photo-catalytic activity for synchronous degradation of heavy metal ion and organic pollutant under visible light.
