摘要: Reduplicate utilization of surfactants is a key factor for Surfactant-Enhanced Remediation (SER) technology to reduce its high operation costs. In order achieve the reuse surfactants, this study attempted construct novel reversible solubilization system SER. Three typical polycyclic aromatic hydrocarbons (PAHs) pyrene, phenanthrene, and acenaphthene were controllably solubilized released by mixed micelles composed redox-active cationic surfactant (11-Ferrocenylundecyl) trimethylammoniunm bromide (FTMA) conventional nonionic Tween80. Solubilization PAHs assumed be controlled changing redox states FTMA. Cyclic voltammograms tests FTMA showed oxidation reduction potential 0.4570 0.4068 V, respectively, peak currents ratio FTMA+ was 1.26, verified that possesses electrochemically property. FTMA-Tween80 solutions, CMC values demonstrated nonideal interaction between two surfactan...
