▎ 摘　　要

NOVELTY - Preparing microorganism-loaded graphene aerogel metal organic framework composite material comprises: (i) mixing the graphene oxide solution and ascorbic acid, reacting under boiling water bath environment, ice bath environment, room temperature environment and boiling water bath environment, freeze-drying and subjecting to thermal annealing treatment to obtain graphene aerogel; (ii) immersing the graphene aerogel in silane coupling agent solution and terephthalic acid solution to obtain carboxylated graphene aerogel; (iii) self-assembling the ferric chloride ethanol solution and trimesic acid ethanol solution, then self-assembling the carboxylated graphene aerogel through layers to obtain graphene aerogel metal organic framework composite material; and (iv) loading the microorganism on the surface of graphene aerogel metal organic framework composite. USE - The microorganism-loaded graphene aerogel metal organic framework composite material is useful for azo dye treatment (claimed). ADVANTAGE - The azo dye has good absorbing and degrading effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) processing azo dye, comprising preparing microorganism-loaded graphene aerogel metal organic framework composite material, adding azo dye solution into the microentrained graphene aerogel metal organic framework composite material; and (2) carboxylated graphene aerogel.
