(A) Pseudo first-order kinetics model (Conditions; pH 6, AFMC dose = 100 mg, contact time:90 min; concentrations: 100–600 mg/L). (B) Pseudo second-order kinetics model (Conditions; pH 6, AFMC dose = 100 mg, contact time:90 min; concentrations: 100–600 mg/L). (C) Elovich kinetics model (Conditions; pH 6, AFMC dose = 100 mg, contact time: 90 min; concentrations: 100–600 mg/L). (D) Fractional power kinetics model (Conditions; pH 6, AFMC dose = 100 mg, contact time:90 min; concentrations: 100 – 600 mg/L). (E) Intraparticle diffusion model (Conditions; pH 6, AFMC dose = 100 mg, contact time: 90 min; concentrations: 100–600 mg/L). (F) Liquid film diffusion mechanism model (Conditions; pH 6, AFMC dose = 100 mg, contact time: 90 min; concentrations: 100–600 mg/L). (G) Schematic diagram of the adsorption of MG dye onto AFMC (AFMC is depicted by its AFMC SEM morphology).
