Tuning the structure of N-methyldiethanolamine-based deep eutectic solvents for efficient and reversible SO2 capture

Abstract

The SO2 absorption capacity of MDEA-Im (1 : 1) was 0.471 g SO2 g−1 DES at 293.2 K and 2000 ppm. The addition of Im increased the absorption sites, making it more effective to capture SO2.
