The kinetics of vanillin sorption by a strong basic anion-exchange resin is studied in static conditions. The kinetic curves of this important representative of hydroxybenzaldehydes sorption by gel anion-exchange resin AV-17-8 have been obtained at various concentration of solution. Based on the kinetic curves in the Boyd-Adamson coordinates the limiting stage of vanillin sorption by the considered anionexchange resin is estimated. The influence of temperature on hydroxybenzaldehyde uptake is revealed; the activation energy of the process is calculated.
