Removal of malathion insecticide from aqueous solution by the integration of persulfate process and magnetite nanoparticles loaded on carbon (Fe3O4@CNT) in the presence of ultraviolet radiation

Abstract

Malathion is one of the most common insecticides in the world, and its persistence in aquatic environments poses a serious threat to human health and ecosystems. In this study, a combined process of persulfate and magnetite nanoparticles loaded on carbon (Fe₃O₄@CNT) in the presence of ultraviolet light was used to decompose malathion as a chemically resistant compound in contaminated water. Fe3O4@CNT was synthesized, and then characterized and characterized using XRD refraction, electron microscopy (FESEM), Fourier-transform infrared spectroscopy (FTIR), and Brunauer-Emmett-Teller. In this hybrid process, the decomposition of malathion occurred at pH =5, 2 mmol persulfate, and 0.4 g of Fe₃O₄@CNT at 60 minutes. The results of sconing experiments showed that sulfate, hydroxyl, and ultraviolet radicals are involved in the optimum decomposition of malathion and this process was able to purify the malathion from the water.
