Abstract
We explored a novel cloud point foaming technique to separate nonionic surfactant from aqueous solutions with a wide range of surfactant con centrations. The phase transformation of nonionic surfactant micelles at the cloud point changes the foaming behavior of surfactant solution s during foaming and results in excellent separation efficiency in ter ms of the volume reduction ratio compared to foaming at room temperatu re.
