H2O and CO2 sorption in ion exchange sorbents: distinct interactions in amine versus quaternary ammonium materials

TL;DR

This paper compares how two different ion exchange sorbents, one with primary amines and the other with quaternary ammonium groups, interact with water and carbon dioxide, revealing distinct sorption mechanisms.

Contribution

It provides a comparative analysis of H2O and CO2 sorption in amine versus quaternary ammonium ion exchange materials, highlighting their different interaction behaviors.

Findings

Distinct sorption interactions observed between amine and QA materials.

Different affinities for H2O and CO2 in the two sorbent types.

Insights into the mechanisms governing sorption in ion exchange materials.

Abstract

This study investigates the H2O and CO2 sorption behavior of two ion exchange sorbents: a primary amine and a permanently charged strong base quaternary ammonium (QA) with (bi)carbonate counter-anions.
