Abstract
Knowing the interactions between a solute and an adsorbent is of great importance for the design of various green processes which utilize supercritical carbon dioxide (sc-CO2) as a solvent. In this work, by means of supercritical fluid chromatography (SFC) the thermodynamics of such systems have been studied. A wide range of polar and nonpolar solutes was used whereas methanol acted as the modifier. The retention data for various systems on four silica matrices was collected at various pressures, temperatures and modifier concentrations by SFC. Subsequently, two different types of retention models, one focusing on solute properties and the other modifier effects, were developed with the goal to generate a more accurate description of the solute-solid-interactions in sc-CO2.
