Magnetic separation of green synthesized Fe3O4 nanoparticles on photocatalytic activity of methyl orange dye removal

The most frequent method of removing malignant growth-causing tones from current effluents before releasing them into water sources such as rivers, lakes, and groundwater has become standard. Traditional waste-water treatment frameworks have trouble getting rid of these contaminants. This is a unique flavonoid that uses Fe3O4 nanorods as photocatalytic agents to corrupt material tone in the watery stage utilizing observable light enlightenment. Green technique was used to amalgamate CAF@Fe3O4 nanorod like gems. Disappearance of the bright (UV) maintenance top at 565 nm confirmed the elimination of Methyl orange tone. After 110 minutes, the sensational shading disposal of Fe3O4 nanorod was observed to be 100%. This is due to photochemical redox process and the use of Fe3O4 nanorods with a high energy gap of flavonoids. The findings show that Fe3O4 rod-like gems manufactured using green technology are extremely valuable in the photocatalytic annihilation of hazardous contaminants.
