Abstract
The mechanism of interaction between inorganic substances and thin layers of microcrystalline cellulose and silica gel is considered. It is observed that the majority of the phenomena associated with the chromatographic behaviour of inorganic substances are not in agreement with the hypothesis of a partition mechanism on cellulose, nor with the ion-exchange mechanism on silica gel. It is concluded that the mechanism of interaction between inorganic substances and cellulose or silica gel is based on adsorption, due to electrostatic forces, primarily through hydrogen bonds between OH-groups of the adsorbent and basic ligands of inorganic complexes. The chromatographic process comprises a continual dynamic adsorption—desorption equilibrium of the complexes between the mobile phase and the stationary phase.
