Green Solvents for Liquid-Liquid Extraction: Recent Advances and Future Trends

The use of environmentally friendly solvents for liquid-liquid extraction offers a promising avenue for promoting sustainability in various industries. Green solvents, including ionic liquids, deep eutectic solvents, supercritical fluids, and biobased solvents, offer several advantages compared to the traditional solvents in the present time. These solvents possess properties such as low toxicity, biodegradability, and reduced environmental impact, making them highly desirable for liquid-liquid extraction processes. Through careful adjustments in composition and physicochemical properties, these solvents can be customized to achieve efficient and selective extraction of desired compounds. Additionally, recent advances in green solvents often contribute to improved energy efficiency, reduced waste production, and the potential for developing novel products with unique characteristics. By embracing green solvents for liquid-liquid extraction, industries can actively contribute to sustainable development, minimize environmental harm, and support the transition towards an eco-friendlier future.
