The homogeneous particle diffusion model (Eq. (6)) was subsequently
applied to determine the effective diffusion coefficient for
pyridine adsorption on MN 200 and MN 500 at various conditions,
by making least-squares fit between this equation and the experimental
adsorption kinetic data (q vs t profiles) of the micropore
diffusion region indicated by the Weber-Morris plot to meet the
minimised average relative deviation in percentage (ARD):
