Abstract
A mathematical model for description of the sorption capacity of ion exchangers on alkaline compounds protonizable in aqueous solutions (exemplified by ammonia, mono-, diand triethylamine) was proposed. The Henry’s constants for these substances were experimentally determined. The model accounts for the concentration and acid-base properties of the sorbate, relative air humidity, acid-base properties and exchange capacity of the ion exchanger, as well as spatial availability of functional groups for interaction under conditions of limited permeability of polymeric ion exchanger. The applicability of the model is illustrated by processing the experimental results on the sorption of ammonia and ethylamines by fibrous carboxylic and sulfonic cation exchangers. Good agreement between the calculated and experimental data is observed.

Summary
Ранее нами была показана эффективность таких материалов при очистке воздуха от аммиака и этиламинов [8,9,10,11,12]. Нами экспериментально исследованы равновесия систем «водный раствор–газовая фаза» для указанных веществ в статических условиях при 25±0,1 °С и рассчитаны константы Генри с учетом констант их диссоциации, так как часть аммиака и аминов находятся в водном растворе в протонизированном состоянии, а закон 1. Зависимость концентрации неионизированных форм аммиака и аминов в растворе от их концентрации в воздухе при 25 °С: а – аммиак; b – этиламин; c – диэтиламин; d – триэтиламин
