英文摘要	SO2 absorption capabilities of DEGDME+H2O system with different compositions were systemically investigated. The DEGDME+H2O system exhibited superior SO2 absorption capability and optimal desorption property with a desorption rate of higher than 94% under the desorption conditions. In addition, it has been demonstrated that the DEGDME+H2O system possessed remarkable SO2 absorbing and releasing capability after multiple recycles. Moreover, GLE data were measured for dilute SO2 in the system of DEGDME+H2O, in which SO2 partial pressures were determined in the range of 0 to 140 Pa. By fitting of GLE data, HLC, Delta H, Delta S and Delta G of SO2 absorption process were obtained. UV, FTIR, H-1-NMR, and C-13-NMR spectra of absorbing systems in the SO2 absorption processes were studied to elucidate the absorption mechanism. On the basis of the spectral results, the intermolecular hydrogen bonding and SaEuro broken vertical bar O interaction between SO2 with the absorption system were discussed.; National Natural Science Foundation of China [21166017]; Program for New Century Excellent Talents in University [NCET-12-1017]; Inner Mongolia Science and Technology Key Projects; Program for Grassland Excellent Talents of Inner Mongolia Autonomous Region; training plan of academic backbone in youth of Inner Mongolia University of Technology; SCI(E); ARTICLE; tadzhang@pku.edu.cn; xhwei@pku.edu.cn; 12; 3493-3503; 33
