NOVELTY - Treating waste water involves putting 5 milligram/millimeter of carboxylated graphene in 1 liter of oxidized graphene aqueous solution, adding 2 grams of sodium hydroxide, 2 grams of chloroacetic acid in oxidized graphene aqueous solution, mixing and reacting for 4 hours, separating, washing to obtain the graphene oxide product, mixing 2 grams of acrylamide polymer graft graphene oxide, graphene oxide product and acrylamide oligomers in dimethyl sulfoxide (DMSO), adding 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI) where the ratio of DMSO, graphene oxide product, acrylamide oligomer. USE - Method for treating waste water (claimed). ADVANTAGE - The waste water treatment method enables to reduces production cost and can effectively remove benzene and heavy metals from waste water. DETAILED DESCRIPTION - Treating waste water involves putting 5 milligram/millimeter of carboxylated graphene in 1 liter of oxidized graphene aqueous solution, adding 2 grams of sodium hydroxide, 2 grams of chloroacetic acid in oxidized graphene aqueous solution, mixing and reacting for 4 hours, separating, washing to obtain the graphene oxide product, mixing 2 grams of acrylamide polymer graft graphene oxide, graphene oxide product and acrylamide oligomers in dimethyl sulfoxide (DMSO), adding 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI) where the ratio of DMSO, graphene oxide product, acrylamide oligomer, EDCI is 1liter:8grams:90grams:50grams, refluxing the reaction at 45 degrees C, separating and washing to obtain acrylamide polymer graft oxidized graphite alkene, treating with acrylamide polymer graft graphene oxide, 10 grams of polyacrylamide, 14 grams dimethyl allyl ammonium chloride, reducing the temperature at normal room temperature, adding 40 grams of silicate and 2 grams of sodium bicarbonate and mixing uniformly to obtain the desired product.
