Abstract

A system weak-base anion exchanger – solution of vanillin in equilibrium conditions is studied
in this article. Based on the analysis of the sorption isotherms of the substituted hydroxybenzaldehyde the
multilayer nature of the uptake is shown. The equilibrium characteristics of the process have been
calculated
