Effect of working conditions on EL removal efficiency and on the biosorption capacity (A): influence of pH (EL solution volume: 10 mL; EL initial concentration: 60 mg/L; biosorbent dose: 2 g/L; room temperature); (B): influence of biosorbent dose (EL solution volume: 20 mL; EL initial concentration: 60 mg/L; pH: 2; room temperature); (C): influence of EL initial concentration (EL solution volume: 30 mL; biosorbent dose: 2 g/L; pH: 2; room temperature); (D): influence of temperature (EL solution volume: 10 mL; EL initial concentration: 60 mg/L; biosorbent dose: 2 g/L; pH: 2).
