Adsorption energy distributions: Theory and applications in liquid chromatography

Journal of Chromatography Open
In liquid chromatography (LC), adsorption heterogeneity arises from the distribution of adsorption sites on stationary phases with varying interaction energies, affecting retention and separation performance.

Measurement of adsorption of a single component from the liquid phase : modelling investigation and sensitivity analysis [PDF]

, 2008
In this work, we consider an alternative approach for the measurement of adsorption from the liquid phase. Consider a mixture consisting of a non-adsorbed component (B) and an adsorbed component (A) present at some low concentration. Initially, a feed of

Dynamics of BaCl2-NH3 adsorption pair [PDF]

, 2009
To obtain accurate kinetics of adsorption pairs, dynamic tests of a composite adsorbent material (BaCl2 impregnated into a vermiculite matrix) and ammonia were performed on small samples under isothermal conditions and on a larger quantity in a ...

Hydrophobic interaction chromatography [PDF]

, 2011
Most proteins and large polypeptides have hydrophobic regions at their surface. These hydrophobic ‘patches’ are due to the presence of the side chains of hydrophobic or non-polar amino acids such as phenylalanine, tryptophan, alanine and methionine ...

Investigation on Separation of 99Mo from Low Enriched Uranium Target by Al2O3 Chromatography

Journal of Isotopes, 2021
Al2O3 chromatography is usally used for separation and purification of 99Mo in the production process of fission 99Mo. To establish the separation process for fission 99Mo from low enriched uranium (LEU) target by Al2O3 chromatography, the effect of 99Mo
