Abstract:

Photodegradation of malachite green (MG) as the model molecule with TiO2 catalyst by microwave discharge electrodeless lamps (MDELs) was investigated.The effects of different parameters in photodegradation of MG, such as MDEL shape, microwave power, initial solution concentration, and catalyst dosage were discussed.Additionally, the photodegradation of congo red, acid black, acid fuchsine and salicylic acid with anatase TiO2 catalyst were investigated under the optimal reaction condition.The results showed that the MDEL is a new treatment method for enhancing photodegradation of organic contaminants with TiO2 catalyst.
