Oxidation of Vanillic acid as a model of polyphenolic compound present in olive oil wastewaters. II. Photochemical oxidation and combined ozone‐UV oxidation

The chemical oxidation of Vanillic acid, a polyphenolic compound present in wastewaters from the olive oil production, is studied by the action of UV radiation and the combination of ozone and UV radiation. The operating variables considered were the temperature, pH, and initial Vanillic acid concentration, plus ozone concentration in the combined experiments. In both processes, the specific kinetic parameters were determined and correlated as a function of the temperature: the quantum yields for the photochemical oxidation, and the apparent kinetic constants for the combined oxidation.

Key words:

• Vanillic acid
• UV radiation
• advanced oxidation processes (AOP)
• ozone
• quantum yields
• apparent kinetic constants
