Table 3. CO₂ Uptake for IER after Exposure to Dry Concentrated CO₂, Wet Concentrated CO₂, and Post-Processing in Humidified N₂.

	q_CO₂^a adsorption uptake (mol/kg_IER)
condition	dry	wet
120 °C, 72 h, 80%^b	1.97	2.10 (2 vol % H₂O)
150 °C, 72 h, 80%^b	1.69	1.81 (1.8 vol % H₂O)
150 °C, 72 h, 100%^c	1.66	1.80 (1.8 vol % H₂O)

q_CO₂ = 2.15 for the undegraded IER, measured at 40 °C under 15% CO₂/N₂.

Concentrated CO₂ streams were humidified using a water column controlled at 23 °C.

Degraded sample was collected, then treated in a flow of N₂ at 150 °C containing 0.6% RH for 24 h.
