The sorption of quercetin by high-basicity anion exchangers

The sorption of quercetin on anionites with various porosities in the OH⁻ and Cl⁻ forms was studied under static conditions. The equilibrium (distribution coefficients K _p) and kinetic (effective diffusion coefficients D _eff) parameters of quercetin sorption on AV-17-2P and AV-17-6M anionites in the Cl⁻ and OH⁻ forms were calculated. The mechanism of quercetin interactions with the anion exchangers was studied by electron microscopy and IR spectroscopy. Original Russian Text ? N.A. Udalova, S.I. Karpov, V.F. Selemenev, I.A.
