Those membranes offer efficient hydrogen separation, by hindering the hydrogen pore diffusion
through the selective adsorption of hydrocarbons.
This implies that the diffusion mechanism of MG dye onto NOAC is operated by pore diffusion
which is the only rate controlling step and not film diffusion.
Then solute movement takes place by pore diffusion
from surface of the particle into interior site.
Investigation of pore diffusion
hindrance of monoclonal antibody in hydrophobic interaction chromatography using confocal laser scanning microscopy.
D = effective pore diffusion
coefficient in spherical pellets, [m.
This suggests that the overall mechanism of reaction is predominantly pore diffusion
The definition of a pore diffusion
coefficient partially overcomes this problem.
t) indicates pore diffusion
coefficient (D2) from the equation 17.
The sharply rising part is the external surface adsorption stage while the second linear part is the gradual adsorption stage where intra-particle or pore diffusion
To formulate a generalized model corresponding to the dispersion flow, surface diffusion and pore diffusion
mechanism, following assumptions are made:
and the relation between the pore diffusion
Moreover, the deviation of plot from the origin in intraparticle diffusion model indicated that the adsorption was not controlling by pore diffusion
