- •
Grafted-diethanolamine adsorbs selectively, quantitatively and reversibly ppm SO2 in CO2.
- •
Material with 1.75 mmol/g amine adsorbs 2.84 at 23 °C in the presence of 1% SO2/N2.
- •
The SO2 adsorption capacity is unchanged in the presence of oxygen under dry condition.
- •
The SO2 uptake increased significantly in the presence of water vapor.
