Abstract
Adsorption isotherm of deoxyadenosine from a water-enriched mixture of water and methanol on silica gel with reverse C-18 phases was measure d using high-performance chromatography. It was shown that at low conc entrations (within the range of 0.1 to 10 mu g/cm(3)) the adsorption i sotherm is most satisfactorily approximated by the Freundlich equation . Analysis of the data available on thymine adsorption confirms that t he Freundlich equation may be employed in the range of low concentrati ons to approximate the isotherm of adsorption on silica gel with rever se phases in the case of water-enriched mobile phases.
