Preparation of graphene-slag-based conducting functional composite material and application of graphene-slag-based conducting functional composite material in sewage treatment

摘要: The invention discloses a preparation method of graphene-slag-based conducting functional composite material and application the in sewage treatment. Graphene is compounded with blast-furnace slag powder; granulated gel base body prepared; two-dimensional graphene overlapped three-dimensional porous to form communicated graphene. comprises following steps: industrial solid waste powder as raw materials, carrying out chemical reaction together sodium hydroxide solution stirring device slurry; molding maintaining obtain material. When applied simulation wastewater degradation employing basic purple 5BN, optimal rate can reach 91.16%; an overall technology equipment are simple, free emission exhaust gas, liquid or waste; green large-scale production be reached.
