Effect of material dosage on CR adsorption capacity onto EG@MnFe2O4 (a) and MnFe2O4 (b). Experimental conditions: solution volume of 100 mL, and dye concentrations of 20–60 mg/L at pH 4 for MnFe2O4 and pH 6 for EG@MnFe2O4. Experiments were run at room temperature (25°C) during the period of 0–240 min.
