In this thesis, the oxygen-vacancy magnetic graphene-like biochar derived from Vicia ervilia plant (BC-G/Fe3O4) and peroxy-monosulfate activator have been used for the adsorption and degradation of remdesivir and favipiravir antivirals. The structural characteristics of the prepared samples were investigated by various techniques such as X-ray diffraction, Fourier transform infrared spectroscopy, X-ray scattering spectroscopy, scanning electron microscopy, vibrating sample magnetometer, photoluminescence spectroscopy, Raman spectroscopy and nitrogen absorption and desorption. Took The results showed that the biochar material has a high surface area, and as a result, it exhibits a suitable adsorption-oxidation property for removing antiviral drugs. Also, its strong magnetic properties lead to easy separation based on the magnetic field. Factors affecting the absorption-oxidation process such as pH, dose catalyst, oxidant concentration, antiviral concentration and temperature were investigated and optimized with response surface method (RSM) and central composite design (CCD) in 22 experiments and 5 levels. took The optimal amount obtained for the highest removal percentage of remdesivir (93%) and favipiravir (98%) when the initial concentration of antivirals is 125 mg/L, the amount of catalyst is 7 mg for remdesivir and 5 mg for favipiravir, the contact time was 120 minutes and the pH was equal to 7. According to the results of this research, BC-G/Fe3O4 catalyst, which has suitable biocompatibility, adsorption-degradation property and suitable reuse, can be used to remove remdesivir and favipiravir antivirals from aqueous environment.
