Chlorinated solvents such as trichloroethylene (TCE) are among the most common soil and groundwater contaminants. If TCE, as a dense non-aqueous phase liquid, is accidently released in the subsurface, its presence would become a continuous source of contamination. Permeable reactive barrier (PRB) is a passive technology for in situ clean-up of groundwater contamination. Among reactive materials filled within PRB, zero valent iron (ZVI) and activated carbon (AC) are widely used reactive materials. ZVI undergoes reductive dechlorination of TCE when containments are in contact with ZVI surface. Therefore, specific surface area of ZVI is highly correlated with high reactivity. In addition, AC with high surface area and multiple surface functional groups is a good adsorbent for removing contaminants. In this study, a process of coating nano zero valent iron (nZVI) onto AC, namely nZVI/AC, was developed. Then evaluation of the synthesized nZVI/AC composites for remediating TCE contamination was conducted.
The results present a successful approach of combining impregnation and borohydride reduction to synthesize nZVI/AC composites. SEM analysis demonstrates that the size of nZVI on AC synthesized under different calcined temperatures is about 50-100 nm. Furthermore, the addition of polyethylene glycol dispersant for preparation of nZVI/AV reveals no effect on nZVI particle size. However, a well dispersion of nZVI on AC is achieved. When comparing nZVI/AC to nZVI on degradations of TCE, nZVI/AC reveals higher percentage of dechlorination than using nZVI only. The used nZVI/AC composites can then be regenerated by carbothermal reduction process which can be an effective method to regenerate the synthesized nZVI/AC composites.
