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

arXiv:2508.03909 · doi:10.1021/acsami.5c12939

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.
