Adsorption kinetics of anthocyanins from elderberry extracts on bentonite

Abstract

Adsorption kinetics of anthocyanins from aqueous extracts of elderberries on bentonite at various concentrations of anthocyanins, mass of bentonite, and temperature was investigated in this work. It was found that the equilibrium adsorption capacities and correlation coefficients for pseudosecond order model are much more reasonable than that of the pseudo-first order model.
