Abstract
Fabrication of photocatalytic TiO2 particles onto PET-g-PAAc fabric has been succeeded by ultrasonic-gamma irradiation methods. Ultrasonic irradiation assisted for good distribution of TiO2 particles onto the surface of PET fabric in a uniform manner at ambient conditions. The product modify PET fabric was characterized by attenuated total reflection-Fourier transform infrared (ATR-FTIR) confirmed the grafting of COOH groups onto PET fabric. SEM images revealed a good dispersed and adherent obtained TiO2 particle onto PET fabric. Results obtained from X-ray diffraction indicating TiO2 (Degussa P25) in the anatase and rutile phases. The degradation process of three different dyes remazol red, amido black and toluidine blue from aqueous solutions by TiO2@PET-g-PAAc was investigated using modified photo reactor. It was found that decoluorization of toluidine blue was 99 % after 60 min. The reused of TiO2@PET-g-PAAc showed that the activity of TiO2@PET-g-PAAc for degradation still remained good which conclude that PET fabric makes TiO2 easily recovered, which overcomes the disadvantage of separation difficulty of common catalyst after or through degradation processing.
