Amino acid adsorption on mesoporous materials: influence of types of amino acids, modification of mesoporous materials, and solution conditions
Article Abstract:
The adsorption behavior of amino acids on mesoporous materials (SBA-15) in relation to amino acid concentration, ion strength and pH is investigated. The results show that for acidic and basic amino acid, the adsorption on SBA-15 depends on the electrostatic interaction with the adsorbents and for neutral amino acids the adsorption depends on hydrophobic interactions with the mesoporous material.

Ion sieving effect in the electrical double layer of porous carbon electrodes: estimating effective ion size electrolytic solutions
Article Abstract:
The adsorption of a variety of globular molecules of nearly spherical shape, with no or negligible dipole moment, into activated carbons of different average pore size is studied. The electric double capacity at moderate concentrations were found independent of both the size and charge of the ions in solutions, as long as the pore size is considerably greater than the ion size.

Assessment of electroosmotic perfusion in capillary chromatographic columns using electrical conductivity
Article Abstract:
Macroporous packing materials support interparticle current flow in chromatographic columns under capillary electrochromatography (CEC) conditions. Columns packed with wide pore media exhibited 2-fold greater conductivities that conventional pore diameter media packed columns.
