(a) Effect of contact time on the sorption of MG by the X-Com-ceramsite in which the initial concentration of MG was 56.876 mg/L (insert is the removal efficiency of MG under different contact time). (b) Langmuir model, (c) Freundlich model, and (d) Van’t Hoff equation fitting the adsorption of MG on the X-Com-ceramsite.
