Cloud point extraction coupled with back extraction: a green methodology in analytical chemistry

Forensic Sciences Research, 2021
Recently, cloud point extraction (CPE) coupled with back extraction (BE) has been suggested as a promising alternative to liquid-liquid extraction. In CPE, non-ionic surfactants in aqueous solutions form micelles and the solution becomes turbid when ...
