Resumen:
The degradation pathways for citric acid (Cit, 5mM, pH 2.8) degradation by TiO2-heterogeneous photocatalysiswere studied through the analysis of its degradation intermediate products. The most importantproduct 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, theintermediates cannot be photocatalytically degraded.
