Biosorption of Congo Red dye from aqueous solutions using pristine biochar and ZnO biochar from green pea peels

Adsorption of Congo red dye in water by orange peel biochar modified with CTAB

“…Adsorption isotherms can elucidate the interaction between the adsorbed material and the adsorbent and contribute to the understanding of the adsorption process. 29 The Langmuir adsorption isotherm model and the Freundlich adsorption isotherm model were used to analyse the adsorption equilibrium of OBC and NOBC, as shown in Fig. 8 and Table 2.…”
