  • High-Efficiency Absorption of SO2 by a New Type of Deep

    Abstract In this work, a new type of deep eutectic solvents (DESs), EmimCl–EPyBr, was prepared for SO 2 absorption. The liquid DESs were composed of 1-ethyl-3-methylimidazolium chloride (EmimCl) and N -ethylpyridinium bromide (EPyBr), which are common ionic liquids (ILs) with a solid state at room temperature.
