Abstract:
This paper considers mineral compositions and prospects for the processing of natural blue montmorillonite clay, pink Fe (III)-containing clay, and green Fe (II)-containing clay into composite aluminosilicate materials suitable for the sorption of related substances of vegetable oils. New Brønsted and Lewis centers were found on the surface of the materials obtained when solutions of oxalic and succinic acids and sodium carbonate in scientifically-substantiated amounts were used as modifying additives. The established changes in the surface states are in correlation with the assessed affinity degree of active sites towards fatty acids, peroxide compounds, carotenoids, and chlorophylls in vegetable oils (flaxseed, olive, mustard), which are rarely refined in world production. These findings are of practical value for the development of a new direction of medical chemistry. It was revealed that the presence of impure hydromuscovite in natural raw materials and the resulting materials reduces the effect of extracting dyes from vegetable oils.
