Multi-Layer Multi-Component Adsorption Isotherm Model:Theoretical and Experimental Validation

摘要

In liquid chromatography, one of many isotherm models introduced based on theoretical and heuristic backgrounds is selected to analyze and describe the retention behaviors of adsorbates. However, most conventional isotherm models are not suitable in cases that adsorbate mixture shows ununiformed behaviors, e.g. in a certain range isotherm shape is changed from Langmuir-like to anti-Langmuir and vice versa, or some components shows different behaviors. Recently, several researchers introduced multi-layer isotherm models for a single component to express theoretical clues for the mixed isotherm behaviors.
