Benzene removal from waste water using aqueous surfactant two-phase extraction with cationic and anionic surfactant mixtures.


A novel separation technique known as an aqueous surfactant two-phase (ASTP) extraction is a promising method to remove organic contaminants from wastewater. When cationic and anionic surfactants are mixed at certain surfactant concentrations and compositions, the solution separates into two immiscible aqueous phases. One is the surfactant-rich and the… (More)
