Desorption data showed that SO2 can be desorbed easily from EGWs + SO2 at 333 K. Φ1 = 70−90% (volume fraction of EG in EGWs) were considered as reasonable compositions of desulfurization solution. Considering the industrial flue gas desulfurization (FGD) processes, Φ1 = 80% EGW (approximately 0.5 molar fraction of EG) was confirmed as the optimum composition of desulfurization solution. When conventional UV, FTIR, and 1H NMR spectroscopic techniques were used for inspection of spectral changes of SO2 in EGWs, the spectral results suggest that SO2 can interact with EG by hydrogen bonds.
