- Abstract:
- In this paper,magnetic biochar prepared from salix mongolica by a one-step method was used for sulfadiazine sodium removal from aqueous solution.The effects of initial concentration,adsorption time,pH and salt ion concentration on the adsorption were investigated.The results showed the maximum adsorption capacity of MBC for SAS was 248.4 mg/g at 298 K.The adsorption kinetics was best described by Elovich model and the whole adsorption process was controlled by both film diffusion and intraparticle diffusion.The equilibrium data was best fitted by the Freundlich and Koble-Corrigan models.The interaction of the π—π dispersion,the hydrophobic interaction and hydrogen bonding played a role in the adsorption of sulfadiazine sodium onto magnetic biochar.
