Abstract

The kinetic parameters of vanillin sorption by weak-base polyfunctional anion-exchange resin
Purolite A 830 are studied. Based on the dependence of equilibration rate on solution stirring rate, its
concentration, and the radius of sorbent granules it is found that for concentrations of aldehyde up to
1.5 · 10-3 mol/dm3 the limiting stage of sorption is the external diffusion
