Sorption of ethylamines from air by fibrous ion exchangers. 2. Fiban K-4, a weak acid cation exchanger
Abstract
Sorption properties of fibrous weak acid cation exchanger FIBAN K-4 have been investigated for sorption of mono-, di- and triethylamine from air. It has been found that main factors governing sorption effectiveness are: a) relative humidity; b) kinetic factors (amines’ low diffusion speed into the ion exchanger phase). Increased swelling for the ion exchanger in the amine ionic form has been observed. By ab initio quantum chemical calculations it has been shown that water molecules in the ion exchanger are located between amine molecules (ions) and functional groups, forming an intermediate layer.
