Fig. 4: CH3I capture experiments.

a CH3I vapor adsorption and desorption isotherms of EtP5 (purple), MHP (red), MHP-Cl (blue), MHP-Br (orange), and MHP-P5Q (green). Solid symbol: adsorption; open symbol: desorption. b Uptake amount of CH3I at 1 bar and 25 °C and reserved amount after desorption. c Time-dependent adsorption amount of CH3I vapor in EtP5 (purple), MHP (red), MHP-Cl (blue), MHP-Br (orange), and MHP-P5Q (green) at 25 °C. d Saturated CH3I uptake from the air and after exposure to air for 30 days at 25 °C.
