▎ 摘  要

NOVELTY - Treating triazine-ring compound containing waste water involves adding 3.5-5 wt.% of graphene foam to triazine-ring compound containing waste water at room temperature. The reactant mixture is heated to 50-80 degrees C with stirring for 3-10 hours for adsorption reaction. After the adsorption is completed, the resultant is filtered and the filtrate is recycled. The graphene foam is soaked in methanol in mass ratio of 1:2 for 3-5 hours for desorption. The graphene obtained is heated to 35-60 degrees C under protection of nitrogen gas for 1-5 hours to obtain activated graphene. USE - Method for treating triazine-ring compound containing waste water (claimed). ADVANTAGE - The method enables to treat triazine-ring compound containing waste water in simple and cost effective manner which is suitable for large-scale production. The rate of reducing chemical oxygen demand of waste water is greater than or equal to 99% and the method can be used for recovery of triazine-ring compound. DETAILED DESCRIPTION - Treating triazine-ring compound containing waste water involves adding 3.5-5 wt.% of graphene foam to triazine-ring compound containing waste water at room temperature to the triazine ring containing waste water. The reactant mixture is heated to 50-80 degrees C with stirring for 3-10 hours for adsorption reaction. After the adsorption is completed, the resultant is filtered and the filtrate is recycles. The graphene foam is soaked in methanol in mass ratio of 1:2 for 3-5 hours for desorption. The graphene obtained is heated to 35-60 degrees C under protection of nitrogen gas for 1-5 hours to obtain activated graphene for carrying out adsorption-desorption cycle. The methanol solution after desorption is separately collected for further recovery of triazine-ring compound.
