(a) Effect of adsorbent dosage on CV removal percentage (t = 15 min for CV, [dye] = 250 mg/L, dose = 0.025, 0.05, 0.1, 0.15, 0.2, and 0.25 g, pH = 7, T = 25 ◦C); (b) Effect of the initial dye concentration on the adsorption percentage of CV dye (t = 15 min for CV, dose = 0.1 g, pH = 8, T = 25 ◦C); (c) Langmuir isotherm model; (d) Separation factor (RL) vs. initial concentration; (e) Freundlich; and (f) Temkin isotherm model (t = 15 min for CV, [dye] = 25 mg/L, dose = 0.05 g, pH = 7, T = 25◦C).
