A POTENTIAL NOVEL APPROACH FOR IN SITU CHEMICAL OXIDATION BASED ON THE COMBINATION OF PERSULFATE AND DITHIONITE
Liu, Y., Y. Zhang, and A. Zhou.
Science of the Total Environment 693:133635(2019)
A novel combined process that coupled persulfate (PS) and dithionite was tested as a remediation technique for organic contamination, represented in this study by TCE. PS/dithionite was effective but depended on operating parameters, including initial PS and dithionite dosages. The optimal molar ratio of PS/dithionite/TCE was 5/5/1. Sulfate radicals (SO4•-) were the dominant reactive species responsible for TCE degradation in the PS/dithionite system, which increased in the presence of oxygen but was still effective in an anaerobic environment.
