(a) Adsorption of Cd(II) on XLAC in binary metal systems (adsorption experiments, m = 50 mg, V = 50 mL, pH = 5.5, T = 40°C, t = 300 min, revolution rate = 200 revolutions·min⁻¹, = 0.005 mol·L⁻¹, and ranged from 0.0035 to 0.0065 mol·L⁻¹). (b) Adsorption of Hg(II) on XLAC in binary metal systems (adsorption experiments, m = 50 mg, V = 50 mL, pH = 5.5, T = 40°C, t = 300 min, revolution rate = 200 revolutions·min⁻¹, = 0.005 mol·L⁻¹, and ranged from 0.0035 to 0.0065 mol·L⁻¹).
