Pseudo-second-order kinetic model
WebJul 10, 2024 · The \(R^{2}\) values for the adsorption kinetics of the metal ions were higher for the pseudo-second-order model compared to those of the pseudo-first-order model. Thus, it appears that pseudo-second-order model is a better model fitting the kinetics of the adsorption of the metal ions employed in this study (Figs. 14, 15). WebFeb 24, 2024 · The intragranular diffusion model seems to depict a better fitting, compared with the pseudo-first-order kinetic model and pseudo-second-order kinetic model. The kinetic model parameters for cesium adsorption are shown in Table 3 .

WebMar 9, 2024 · A pseudo-second-order model is given as follows: When t approaches zero, the bioadsorption velocity qt / t becomes the initial bioadsorption velocity, and the data obtained in the kinetic study are adapted to the pseudo-second-order model by plotting the graph of t / qt versus t.
Web1 of the first-order kinetic model has a different dimension from k 2 of the second-order kinetic model. For fractional first-order kinetic model, a Monte Carlo method is used to fit Eq. (8) with the experimental data. An initial trial solution is adopted from the fitting value of the first-order kinetic model, i.e:, we start with α ¼ 1, and ¼ 1 WebApr 11, 2024 · However, The adsorption kinetic data of Ni(II) onto BC-HA could be well-described by the Pseudo-second-order model, showing high regression coefcients of R 2 = 0.997 (Table 2).
WebAug 15, 2009 · Since the introduction of pseudo-second-order (PSO) model for the description of adsorption kinetics in 1999, it has been widely applied in liquid-phase adsorption systems. An approaching equilibrium factor (Rw) was defined and deduced from the PSO model in this work. WebMar 19, 2024 · Pseudo-First-order (PFO), Pseudo-Second-order (PSO), Elovich, and Intra-particle (IP) model are some of the kinetics that foretells the adsorbent-adsorbate interaction.
