Sorption of 3-glucosides of six common natural anthocyanidins on anatase

Keywords: Anthocyanins, Sorption, Sorption mechanisms, Anatase, Surface layer structure, Silica gel


In this study, the sorption of 3-glucosides of six common natural aglicones: delphinidin, cyanidin, petunidin, pelargonidin, peonidin and malvidin, on the surface of anatase was studied in comparison with sorption on the surface of silica gel, as a result, a different order of change in the sorption activity of anthocyanins depending on their structure was found. The structure of the (001) face of the surface layer of anatase crystals due to the olation and oxolation of the initial [Ti(OH)4(H2O)2] octahedra upon condensation into three-dimensional grids was proposed.

The mechanisms of sorption of anthocyanins on the surface of sorbents are proposed. Delphinidin derivatives have thehighest sorption activity on anatase.
