NOVELTY - Composite material comprises 46-50 pts. wt. acidified activated carbon, 32-38 pts. wt. polytetrafluoroethylene, 8-10 pts. wt. graphene, 2-6 pts. wt. ferric trichloride, 1-3 pts. wt. poly aluminum ferric chloride, 3-5 pts. wt. gamma -aminopropyltriethoxysilane, 1-3 pts. wt. Raney nickel, 4-6 pts. wt. modified chitosan, 2-4 pts. wt. instant sodium silicate, 1-3 pts. wt. nano-mesoporous molecular sieve, 0.8-1.2 pts. wt. inorganic titanium silicon, 0.6-1 pts. wt. nano titanium dioxide powder, 0.5-0.9 pts. wt. dispersion medium and 0.7-1.1 pts. wt. reducing agent. USE - The composite material is useful for tubular membrane filtration layer of industrial wastewater treatment (claimed). ADVANTAGE - The composite material: is reasonably; has stable structure, large specific surface area, and high adsorption capacity, good thixotropy, thermal stability, plasticity, adhesion and high dry pressure strength; and improves the water purification effect without secondary pollution.
