Determining Active Agents, Stability, and Mechanism of Diazinon Degradation by Magnetic Copper Ferrite Nanoparticles and Potassium Hydrogen Monopersulfate in the Presence of Ozone in Aqueous Solutions

: According to the results obtained thus far, ozone/magnetic copper ferrite nanoparticles (CuFe2O4 MNPs)/potassium hydrogen monopersulfate (KMPS) is capable of totally degrading 20 mg/L diazinon (DZN) with 6 ozone, 0.6 g/L KMPS, and 0.1 MNPs at pH = 7 in min. The experiments showed that concentrations KMPS were more effective than ozone on system efficiency. Moreover, high not very DZN degradation. Furthermore, degradation efficiencies pHs 3, 4, 5, 6, 7, 8, 9, 10 94%, 95.35%, 97.45%, 98.15%, 99.2%, 99.3%, 100%, respectively. solution was so range - 10, had Even within 3 been plummeted, resulting a percentage Besides, could be utilized for up five cycles without any loss catalytic activity. efficiency 99.2% first use 92.1% fifth use. Also, process assessed four real environments showing agricultural drainage urban wastewater percentages 79.1% 77.3%, respectively, better treated river water 93% 88.4%, With determination active agents reaction using scavenging agents, it recognized sulfate radicals, hydroxyl superoxide, singlet oxygen contributed By way, advantageous both superoxide diazinon.
