Removal of some sulfonamides using reused MXene doped to bismuth ferrite (MXene/ BiFeO3) nanocomposite from pharmaceutical industry wastewaters | Catalysis Conferences 2023 | Chemical Engineering Conferences 2023 | Chemistry Conferences 2023
The treatment of three sulfonamides namely sulfadiazine (SDZ), sulfathiazole (STZ) and sulfamerazine (SMZ) were performed via adsorption process to reused MXene doped to bismuth ferrite (MXene/ BiFeO3) nanocomposite. The adsorption activity of MXene/ BiFeO3 nanocomposite was improved by doping of BiFeO3 to the nanocomposite. BiFeO3 facilitate the removal of sulfonamides with high surface area properties. The adsorption kinetics and isotherm models of sulfonamide on MXene/ BiFeO3 nanocomposite exhibited a pseudo-second-order kinetics and Langmuir mode,respectivelyl. MXene/ BiFeO3 nanocomposite was reused 35 times with adsorption yields as high as 97-99% . The effects of MXene doped to bismuth ferrite (MXene/ BiFeO3) nanocomposite concentrations ( 1, 3, 5,7 and 9 mg/l), adsorption time ( 5, 10, 15 and 20 min), sulfonamide concentration ( 50, 100, 200, 400 and 600 mg/l and Ph ( 4, 7 and 10) on the sulphonamid adsorption yields were investigated. Furthermore, BiFeO3/MXene is stable and retains its original properties upon desorption. The maximum sulfadiazine (SDZ), sulfathiazole (STZ), sulfamerazine (SMZ) adsorption yields were 99%, 98% and %99 after 15 min adsorption time, at pH= 7.00 at a MXene/ BiFeO3) nanocomposite concentration of 3 mg/l and at sulphonamide concentrations of 400 mg/l.
