Abstract

The kinetics of a substituted aromatic aldehyde (ethylvanillin) sorption by fiber and granular anionexchange
resins in static conditions is studied. The influence of sorbate concentration on its uptake rate has
been estimated. The comparison of equilibrium time and capacity values for sorbents in different forms
(granule, fiber) has been made. The hybrid kinetic mechanism of this type of organic substances sorption for
fiber as well as for granular sorbents has been revealed based on the kinetic curves of hydroxybenzaldehyde
sorption plotted in the coordinates of Boyd-Adamson equations.
