NOVELTY - Removing atrazine in a water body using nano-zero-valent iron/graphene complex with activated persulfate comprises (i) adding graphene oxide and an ethanol/aqueous solution into a 500 ml three-neck reaction flask, ultrasonically stirring for 20 minutes, adding ferrous salt, stirring continuously for 40 minutes under a nitrogen atmosphere, dropping sodium borohydride solution into the above solution via a peristaltic pump, reacting for half an hour, filtering the mixture by suction, washing with ultra-pure water and anhydrous ethanol for multiple times and drying in a vacuum and (ii) mixing the persulfate with the wastewater containing atrazine uniformly, adding nano-zero-valent iron/graphene complex, oscillating the reaction and degrading the persulfate in the water by the complex activated persulfate. USE - The method is useful for removing atrazine in a water body using nano-zero-valent iron/graphene complex with activated persulfate. ADVANTAGE - The method has good separation rate, stability and is economical.
