“…However, it increased experimentally from 170.0 mg g −1 to 253.2 mg g −1 after 24 hours. Adsorption kinetics were investigated by the widely used pseudo first- 26 and second-order, 27 intraparticle diffusion, 28 and the Elovich 29,30 equations. Mathematical formulas of the above equations and theoretical explanations can be seen in the ESI †.…”
