Description: We have synthesized sorbents based on Silokhrom S-120 silica gel grafted with Ni2+, Co2+, and Cu2+ acetylacetonate layers. Using pH measurements and a Hammett indicator method, we have studied the acid-base properties and composition of donor-acceptor centers on silica gel surfaces before and after modification. We have determined chromatographic retention parameters for test compounds and evaluated the polarity and selectivity of the sorbents. Modification with acetylacetone chelates has been shown to increase the surface acidity of Silokhrom S-120, leading to changes in various types of intermolecular interaction.
