3.3. Results of kinetics and discussion
Adsorption kinetic is investigated to examine the controlling
mechanism for this adsorption process. The pseudo-first order
and the pseudo-second order kinetics equations basically
contain all the process. By using both kinetics equations, the
simulation analysis of experimental data reveals the truth of
the adsorption kinetic mechanism of glyphosate on resin
D301. To further study on the adsorption kinetics, models of
both Elovich and intraparticle diffusion are applied, simultaneously.
The results are listed in Table 3. Table 3 shows that
the correlation coefficient value of the pseudo-second order
kinetic equation is higher than that of other models. Therefore,
