- Abstract
Diazinon (O, O-diethyl-O-[6-methyl-2-(1-methylethyl)-4-pyrimidinyl] phosphorothioate) is one of the most widely used organophosphorus pesticides that are being increasingly detected in water bodies. However, Diazinon is persistent to conventional biological treatment and sole ozonation with lack of hydroxyl radical. Studies on the effective elimination of Diazinon are still quite sporadic and scarce. In this research magnetic graphene oxide/ ozonation (MGO/O3 ) were used to Diazinon removal from aqueous solution. The results of this research indicate that the Diazinon abatement rate was considerably accelerated via the hybrid MGO/O3 which can generate abundant hydroxyl radical, compared to sole ozonation according to scavenging runs, hydroxyl (·OH) radical was obtained to play a main role in synergistic degradation of Diazinon. All results showed that the MGO/O3 hybrid system is an efficient and suitable option for the removal of emerging organic contaminants from the aqueous solutions.
