Degradation reactions of different contaminants

Electron acceptorsDegradation reaction equation
Glucose C6H12O6 + 24C = O + 12H2O → 6HCO3 + 24C-OH + 6H+
24C-OH + 24Fe(III) → 24Fe(II) + 24C = O + 24H+ 
Formic acid HCOO + 2C = O + H2O → HCO3 + 2C-OH
2C-OH + 2Fe(III) → 2Fe(II) + 2C = O + 2H+ 
Pyruvic acid CH3COCOO + 2C = O + 2H2O → CH3COO + HCO3 + 2C-OH + H+
2C-OH + 2Fe(III) → 2Fe(II) + 2C = O + 2H+ 
Benzoic acid C6H5COOH + 30C = O + 19H2O → 7HCO3 + 30C-OH + 6H+
30C-OH + 30Fe(III) → 30Fe(II) + 30C = O + 30H+ 
Phenol C6H5OH + 28C = O + 17H2O → 6HCO3 + 28C-OH + 6H+
28C-OH + 28Fe(III) → 28Fe(II) + 28C = O + 28H+
