What is Green iron oxide (GIO) utilized for reductive removal of As(III) and methyl red (MR) with non-thermal plasma via synergistic catalytic study about?

In this research, the suggested non-thermal plasma was used for the removal of inorganic (As(III)) and organic (MR) compounds with waste material synthesized nano-particles, such as green iron oxide (GIO) for environmental safety. The plasma-generated RONS, such as O, OH • , H2O2, and NOx, have been employed for the oxidation and reduction of As(III) and Fe3O4. These plasma reactive species H2O2 and NOx were found to be the maximum in the DI water, which are 144.24 μM and 111.86 μM, respectively. The arsenic removal capacity qmax is 4.69 mg/g. However, the yield of As(III) absorbed on the surface of GIO was discovered, which is a maximum and minimum of 14.08 and 8.53 g/kWh, respectively. Meanwhile, the GIO catalytic enhancement study was proved by the removal of organic compounds, such as MR via degradation. Although, the pH for MR was found to be 3.0–3.5 under plasma irradiation. The characterization was performed for the crystallinity, surface, elemental, functional groups, surface area, mass spectrum, and XPS. Whereas, the kinetic study and isotherms are performed at the rate-limiting constant R2 ≈ 1, which is a monolayer phenomenon. Finally, the arsenic was able to be removed l
