FERRATE(VI) BASED CHEMICAL OXIDATION FOR THE REMEDIATION OF AGED PCB CONTAMINATED SOIL: COMPARISON WITH CONVENTIONAL OXIDANTS AND STUDY OF LIMITING FACTORS
Monfort, O., M. Usman, I. Soutrel, and K. Hanna.
Chemical Engineering Journal 355:109-117(2019)
This study tested the efficiency of ferrate(VI) (FeVI) to degrade PCBs in contaminated soil under various experimental conditions. Integrating Fe(VI) and conventional oxidants improved degradation efficiency, which was highest (40% removal) using Fe(VI)/HSO5-. To evaluate if soil factors limit PCB degradation, the role of carbonate content, overall soil matrix, and PCB availability was assessed. An increase in PCB availability improved treatment efficiency (45% removal by Fe(VI) alone). Results indicated that Fe(VI) displayed higher suitability and efficiency for PCB remediation as compared to the conventional oxidants. The study also proposes potential degradation mechanisms.
