Summary:A series of tetraglyme&#8315;sodium salt ionic liquids have been prepared and found to be promising solvents to absorb SO<sub>2</sub>. The experiments here show that [Na&#8315;tetraglyme][SCN] ionic liquid has excellent thermal stability and a 30% increase in SO<sub>2</sub> absorption capacity compared to other sodium salt ionic liquids and the previously studied lithium salt ionic liquids in terms of molar absorption capacity. The interaction between SO<sub>2</sub> and the ionic liquid was concluded to be physical absorption by IR and NMR.
