New users of ionic liquids are often worried about the environmental fate of ionic liquids after use. These concerns are real because ionic liquids are usually soluble in water (because they are ionic) and can dissolve in conventional organic solvents (depending on the carbon content). However a study by Prof. Coutinho and coworkers in 2012 provides useful insights on possibility for recovery most of the ionic liquids through the use of common aluminum salts. Details of the study are captured here...
