Adsorption of phenols on microdisperse sintered detonation nanodiamond (MSDN) from water–acetonitrile solutions was investigated using high performance liquid chromatography (HPLC). Parabolic dependence between retention and organic solvent content in mobile phase was observed. The influence of physicochemical characteristic solutes including molecular volume (V), dipole moment (μ), hydrophobicity (logP), polarizability (α) and molecular refractivity (MR)) of phenols on their adsorption from water–acetonitrile solutions was investigated. Single- and multi-parameter correlations between retention factor and various physicochemical characteristics of sorbates were obtained. The effect of column temperature on adsorption of phenols on UDD was investigated. The changes in ΔH and ΔS for competitive adsorption of the test sorbates were determined.
