Abstract

The influence of acidity on vanillin and ethylvanillin sorption from aqueous solutions by weak-base
anion-exchange resin with polyamines as functional groups is revealed. The features of ethylvanillin sorption
in equilibrium conditions are studied. The sorption mechanism of hydroxybenzaldehyde uptake is estimated
based on a formal selection of sorption equations.
