Adsorption kinetic studies are significant to determine the efficiency of adsorption and also discover the mechanism and rate-defining step of a chemical reaction. The fitness of experimental data to pseudo-first-order, pseudo-second-order, intraparticle diffusion, and the Boyd model was investigated to explain the adsorption process. All kinetic model parameters and values are shown in Table 3. Based on R² value, the pseudo-second-order model (Figure 6(a)) is more close-fitting than the pseudo-first-order model (Figure 6(b)), and for the pseudo-second-order model, the experimental adsorption capacity q_e,exp. is adjacent to the calculated adsorption capacity q_e,cal (Table 3).
