Popis:	The adsorption of the zinc octa-4,5-carboxyphthalocyanate modifier on known HPLC sorbents of different types (Silasorb-C18, Diasorb-130-C4, Diasorb-130-C16, Spheron C 100 (LC), Spheron C 1000, and Hema S 1000 QL) was studied. The optimum conditions were determined for the modification of the sorbents in the static and dynamic modes. The mechanism of the retention of modifiers and adsorbates was considered, and the amount of the modifier on the surface of the adsorbents was calculated. The effect of the modifier on the retention of adsorbates was demonstrated. Mobile phases were selected for the selective and efficient separation of model mixtures of phenols.
