The compositions and structure of REE’s acetylacetonate and benzoylacetonate were studied. Mesoporous sorbents with applied layers of these complexes were synthesized, their surface and chromatographic polarity were investigated in comparison with the original Chromaton N-AW+Si02- It is established that the surface modification by these complexes leads to a decrease in the specific surface with a small change in the average size and volume of pores. The General increase in the polarity of modified sorbents in comparison with the initial one is noted. It is found that acetylacetonates exhibit greater polarity, the greatest value among all presented complexes belongs to acetylacetonate Yb(III).
