Moisture swing adsorption (MSA) is considered as a promising negative emission technology for CO₂ direct air capture (DAC), but its kinetics description remains challenging due to the synergistic and interdependent sorption behaviors of CO₂ and H₂O. This study initially proposes H₂O-informed MSA kinetics characterization for D290 ionic exchange resin. By investigating the apparent sorption characteristics based on customized experimental platform, the research finding gives insights into the dynamic interdependence for binary-sorption.
