Title : Removal of some sulfonamides using reused MXene doped to bismuth ferrite (MXene/ BiFeO3) nanocomposite from pharmaceutical industry wastewaters

Abstract:

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.
