The applicability of silica gels, modified with ketoimine groups, in solid-phase extraction was tested. The surface characteristics of the modified silica was determined by elemental analysis, NMR spectra for the solid phases (29Si CP MAS NMR), analysis of pore size distribution of the silica support, and nitrogen adsorptiondesorption. The newly proposed sorbents with ketoimine groups were used for extraction of endocrine-disruptor compounds, extracted from water and powder milk. The properties of the sorbents were compared with commercial C18 ones.
