Ever since the discovery of the first "Ionic Liquid" (ethyl ammonium nitrate) by Paul Walden in 1914, it has always been an intriguing scientific area for scientists worldwide. Over the past two decades, ionic liquids have received significant attention and are being extensively researched upon. The amount of research carried out in this particular field has increased exponentially and the trend is likely to continue given the tough advantages possessed by ionic liquids. Ionic liquids are being investigated and studied in a plethora of fields some of which include chemical engineering, extraction chemistry, medicinal chemistry, environmental science, material science and many more. Conventionally, volatile organic solvents have been the frontrunner as the choice of solvent in the extraction and synthesizing processes. However, these solvents have a detrimental impact on the environment and often result in toxic byproducts. Ionic liquids as an alternative to these solvents possess several attractive and unique features such as non-volatility, non-flammability, low nucleophilicity and several others that make ionic liquids as "Green solvents" the most suitable and ideal substitute. To assess and explore the potentiality of ionic liquids as an asset in extraction techniques, there arises a need for a consolidated report that elucidates the capabilities of ionic liquids. In this review, an attempt is made to compile all the applications of ionic liquids as an extractant in several fields to fill all the knowledge gaps for the professionals from the science world to give a verdict and potentially overcome all the shortcomings and pave a way towards a sustainable and green future.
