ISCO Treated Compounds and Oxidant Persistence
| Oxidant | Reacts well with: | Does not react well with: | Does not react with: | Persistence |
|---|---|---|---|---|
| H2O2/Fe | BTEX, TCA, PCE, TCE, DCE, VC, CB, phenols, 1,4-dioxane, MTBE, TBA, high explosives | DCA, CH2Cl2, PAHs, carbon tetrachloride, PCBs | CHCl3, pesticides | Easily degrades in contact with soil/groundwater unless inhibitors are used |
| Ozone | BTEX, PCE, TCE, DCE, VC, CB, phenols, MTBE, TBA, high explosives | DCA, CH2Cl2, PAHs | TCA, carbon tetrachloride, CHCl3, pesticides, PCBs | Easily degrades in contact with soil/groundwater |
| Ozone/H2O2 | BTEX, TCA, PCE, TCE, DCE, VC, CB, 1,4-dioxane, phenols, MTBE, TBA, high explosives | DCA, CH2Cl2, PAHs, carbon tetrachloride, PCBs | CHCl3, pesticides | |
| Activated Persulfate | BTEX, PCE, TCE, DCE, VC, CB, phenols, 1,4-dioxane, MTBE, TBA | PAHs, explosives, pesticides | PCBs | The oxidant is very stable |
| Permanganate | TEX, PCE, TCE, DCE, VC, PAHs, phenols, high explosives | Benzene, pesticides | TCA, carbon tetrachloride, CHCl3, PCBs | The oxidant is very stable |
