Table 1 Some important side reactions of H2S in early diagenesisa
(1) | MnO2 + H2S + 2H+ → Mn2+ + S0 + 2H2O |
(2) | 2FeOOH + H2S + 4H+ → 2Fe2+ + S0 + 4H2O |
(3) | 2FeL n 3 - 2n+ H2S + nH+ → 2Fe2+ + S0 + nHL -b |
(4) | Fe2+ + H2S |
(1) | MnO2 + H2S + 2H+ → Mn2+ + S0 + 2H2O |
(2) | 2FeOOH + H2S + 4H+ → 2Fe2+ + S0 + 4H2O |
(3) | 2FeL n 3 - 2n+ H2S + nH+ → 2Fe2+ + S0 + nHL -b |
