AB  - Zero-valent iron/activated carbon (Fe/C) particles can degrade persistent organic 
      pollutants via micro-electrolysis and therefore, they may be used to develop 
      materials for permeable reactive barriers (PRBs). In this study, 
      surfactant-enhanced electrokinetics (EK) was coupled with a Fe/C-PRB to treat 
      phenanthrene (PHE) and 2,4,6-trichlorophenol (TCP) co-contaminated clay soil. An 
      environment-friendly biosurfactant, rhamnolipid, was selected as the 
      solubility-enhancing agent. Five bench-scale tests were conducted to investigate 
      the performance of EK-PRB on PHE and TCP removal from soil as well as the impact 
      of pH and rhamnolipid concentration. The results show that both PHE and TCP, 
      driven by electro-osmotic flow (EOF), moved toward the cathode and reacted with 
      the Fe/C-PRB. Catholyte acidification and rhamnolipid concentration increase 
      improved the removal efficiencies of PHE and TCP. The highest removal efficiency 
      of PHE in soil column was five times the efficiency of the control group on which 
      only EK was applied (49.89 versus 9.40%). The highest removal efficiency of TCP 
      in soil column was 4.5 times the efficiency of the control group (64.60 versus 
      14.30%). Desorption and mobility of PHE and TCP improved with the increase of 
      rhamnolipid concentration when this exceeded the critical micelle concentration. 
      This study indicates that the combination of EK and a Fe/C-PRB is efficient and 
      promising for removing persistent organic pollutants (POPs) from contaminated 
      soil with the enhancement of rhamnolipid.
