Sonophotolytic oxidation Process :
- In the case of photocatalytic oxidation, the most common problem is the reduced efficiency of the photocatalyst with continuous operation.
- This is due to the adsorption of contaminants at the surface and blocking of the UV active sites.
- So a technique for proper continuous cleaning of the surface during the operation is required.
- Ultrasonic irradiation is one of the technique that can be used continually with the UV/solar irradiation.
