Resumen:
The degradation pathways for citric acid (Cit, 5mM, pH 2.8) degradation by TiO2-heterogeneous photocatalysis were studied through the analysis of its degradation intermediate products. The most important product formed was 3-oxoglutaric acid, but several other compounds, like acetoacetic, lactic, pyruvic, malic, glyoxylic, acetic and formic acids plus acetone were found. While citric acid is present, the intermediates cannot be photocatalytically degraded.
