Effective sequestration of levofloxacin from wastewater by biochar-supported manganese dioxide composite: Experimental study and modelling analyses

Manganese dioxide was laden hooked on biochar sourced from chicken feather to obtain a biochar-supported manganese (BSM) composite. In order reduce the costs of acquisition and minimise disposal adsorbents, prepared BSM composite were employed in sequestration Levofloxacin (LEVO) aqueous environment. The physico-chemical features adsorption mechanisms BSM, prior after LEVO molecules revealed by Scanning Electron Microscopy Fourier Transform Infrared spectroscopy techniques. influence parameters including dose, initial concentration, temperature residence time studied. removal significantly influenced all parameters. Equilibrium data has its fitness following order: Redlich-Peterson ˃ Langmuir Freundlich models. maximum capacity for 104.13 mg/g. kinetic analysis indicates best fittings pseudo-second-order model suggesting chemisorption as controlled mechanism. Besides, liquid film intra-particle diffusion had vital process. Exothermic spontaneous nature uptake thermodynamic analysis. findings suggested that show high sorption capacity, recyclability potential towards separation contaminated pharmaceutical wastewater.
