- Abstract:
-
An induction- electro-Fenton system was built with iron and steel as inductive anode and cathode materials, and in situ removal efficiency of fluoranthene (one of the typical PAHs pollutants in soil) by adding sodium alpha-olefin sulfonate (AOS) as an anionic surfactant combined with induction-electro-Fenton method was explored. The addition of AOS higher than the critical micelle concentration (CMC) in the system could improve the efficiency of the electrochemical method in removing fluoranthene from soil. The induction-electro-Fenton system could effectively reduce the differences of fluoranthene removal efficiency in soil space with electric field distribution. The induction-electro-Fenton system added with AOS solution of 4 times CMC could improve the removal efficiency of fluoranthene. The average removal efficiency of fluoranthene was 54.28%, which was significantly higher than that of traditional electrolysis (28.84%) and induction-electro-Fenton method (46.53%).
