Supported ionic liquid membranes

Sulfur dioxide (SO2) and carbon dioxide (CO2) emissions have to be efficiently controlled due to environmental, economic and social demands. An interesting approach for SO2 and CO2 separation/concentration is the use of supported ionic liquid membranes (SILMs). Ionic liquids (ILs) are very interesti

This work studied the use of room temperature ionic liquids (RTILs) based on the 1-n -alkyl-3methylimidazolium cation, in supported liquid membranes (SLMs), in order to use them as membrane materials for separation and enrichment of hydrogen from a gaseous mixture containing H2, CO2, and N2. Differe
