SD: standard deviation, (min⁻¹), (g mg⁻¹ min⁻¹), and (mg g⁻¹ min^−1/2): biosorption rate constants, and (mg g⁻¹ min⁻¹): initial biosorption rates, (min⁻¹): maximum relative biosorption rate, (min): time pointing center of (/2), and (mg g⁻¹): a constant providing information about thickness of boundary layer.
