Enhanced photocatalytic degradation of monocrotophos in aqueous solution over titania hybridised with beta-zeolite.
Photocatalytic degradation of monocrotophos has been carried out in a slurry type batch reactor. The reaction variables were optimised to obtain maximum degradation efficiency. The degradation rate of monocrotophos is significantly higher for acidic solutions than for alkaline solutions. It is also observed that the high concentration environment of the pollutant formed around the hybridised TiO2, enhances the mineralisation rate of monocrotophos. Hence an increase in relative photonic efficiency is obtained.
