H2O2 activation and related reactions. | |
---|---|
H2O2 + Fe2+ → Fe3+ + OH− + •OH | R 1 |
H2O2 + Fe3+ → Fe2+ + + 2H+ | R 2 |
+ Fe3+ → Fe2+ + O2 | R 3 |
•OH + RhB → products k4 = 2.5 × 1010 1/M × s (Buxton et al., 1988) | R 4 |
•OH + [Si] → products | R 5 |
•OH + H2O2 → HO2•− + H2O k6 = 2.7 × 107 1/M × s (Buxton et al., 1988) | R 6 |
•OH + ≡Si → products | R 7 |
2H2O2 O2 + H2O | R 8 |
2H2O2 • OH2 + HO2•− + H2O | R 9 |
H2O2 2 •OH | R 10 |
Note: [Si] is the pseudo-first-order rate constant (ks 1/s) for •OH scavenging by all constituents in solution except the target compound.
