Deep Eutectic Solvents and Their Uses for Air Purification

Chemical compounds released into the air by the activities of industrial plants and emitted from many other sources, including in households (paints, waxes, cosmetics, disinfectants, plastic (PVC) flooring), may affect the environment and human health. Thus, air purification is an important issue in the context of caring for the condition of the environment. Deep eutectic solvents (DESs) as liquids with environmentally friendly properties (non-volatile, biodegradable, non-toxic, cheap, easy to prepare) are a promising solution to this problem. This paper reviews the advances made in the application of DESs as sorbents for the purification of atmospheric and indoor air. The potential of DESs and their subclasses (including SUPRAmolecular Deep Eutectic Solvents, SUPRADESs) applications in air purification processes were also summarized.The authors believe that this review can be useful for future readers as a starting point for research in the field of DESs and their application in air purification.
