second feature that may also strongly constrain the application of the
developed material as efficient adsorbent is the kinetics of the process.
Basically small kinetic adsorption significantly increases the removal
time of the impurity fromthe liquid phase,which directly made the adsorption
process being unfavorable [43]. In this work several kinetic
models including the pseudo-first-order, the pseudo-second-order,
the intra-particle diffusion, and the Elovich kinetic models were used
to test the experimental data.
