NOVELTY - Preparation of graphene-slag based electric conductive functional composite material comprises taking blast furnace slag powder as raw material, placing in stirrer; adding 0.01-0.02 wt.% graphene material, uniformly mixing; taking 3 wt.% solid sodium hydroxide; dissolving in 0.28 wt.% water, adding into stirrer, mixing, reacting; molding for 1 day, adding to standard curing box for 1 day, stripping, adding to standard curing box for 2 days, detecting compressive and flexural strength of test block, crushing test block, and sieving through 70-45 meshes to obtain 0.215-0.325 mm particles. USE - Method for preparing graphene-slag based electric conductive functional composite material used for degradation of alkaline violet 5BN simulated industrial wastewater (claimed). ADVANTAGE - The method is simple and environment-friendly, and has simple device, no waste gas, waste liquid, and waste solid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for degradation of alkaline violet 5BN simulated industrial waste water comprising taking alkaline violet 5BN simulated industrial waste water, transferring into cuvette, measuring initial absorbance using UV-visible spectrophotometer to 580 nm; adding into beaker, placing in dark room for 15 minutes, irradiating using visible light or UV light, centrifugally separating, taking supernatant into cuvette, measuring absorbance using ultraviolet-visible light spectrophotometer; adding liquid and solid composite material into reactor; repeating second and third steps until alkaline violet 5BN simulated industrial waste water absorbency does not change with time, calculating alkaline violet 5BN and organic pollutant degradation rate using formula DE=(Ao-At)/Aox 100%, where Ao is initial absorption wavelength at 580 nm, and At is absorbance at t time after degradation.
