摘要/Abstract

摘要： The development of novel absorbents is essential for SO₂ removal. In this study, a novel ionic liquid (IL, [BHEP][HSO₄]) was prepared, and water was selected as the co-solvent. The density and viscosity of aqueous [BHEP][HSO₄] were measured and the SO₂ absorption performance was systematically investigated. Furthermore, the thermodynamic properties of SO₂ in aqueous [BHEP][HSO₄] were calculated. Additionally, the mechanism of SO₂ absorption in aqueous [BHEP][HSO₄] was confirmed using Fourier-transform infrared and nuclear magnetic resonance spectroscopy. It showed that [BHEP][HSO₄] absorbed 0.302 g·g^-1 (g SO₂/g IL) at an SO₂ partial pressure of 2000 μl·L^-1 at 303.2 K, and the SO₂ desorption enthalpy was -39.63 kJ·mol^-1. The mechanistic study confirmed the chemical absorption of SO₂ in aqueous [BHEP][HSO₄].
