Results and discussion
Any other information on results incl. tables
Guaiacol clearly shows a redox reaction with significant production of CO2. Mineralization of guaiacol also occurs using the mineral iron (III) phase ferryhydrite as the oxidant, although the reduced availability of this form resulted in less CO2 production than when soluble Fe(III) was used. The ratio of the number of moles of Fe(II) produced is estimated to be around 3.5. After 18 h, 0.26 µmol CO2 was produced. During the first reaction step guaiacol is oxidized while Fe(III) is reduced, and o-quinone can be produced. Then a splitting of the quinone ring occurs, producing muconic acid or beta-keto-omega-hydroxycarbonic acid and liberation of CO2. |
