Application of photocatalytic oxidation process using modified TiO2/PBS biocomposite film for dye removal

Abstract

Polybutylene succinate (PBS) has been applying as one of the most recognizable biopolymers for fabrication as a biocomposite film for photocatalyst in the photocatalytic oxidation process. This research, the biocomposite film,was composed of PBS and TiO2 particles, which was used as a model substrate such thyltriethoxysilane in order to modify the photo-catalytic degradation efficiency of the TiO2 embedding throughout the PBS matrix. The results found that the photocatalytic activity efficiency of the TiO2 in the degradation of black dye in wastewater from the textile industry in photoreactor had occurred on the TiO2/PBS biocomposite film at a high amount of TiO2 in the PBS matrix.The physical properties and chemical structures of developed photocatalyst biocomposite films were characterized using XRD, FTIR, UV–visible absorption spectra and SEM analysis. The SEM images indicated the the presence of high homogeneity of the deposition of TiO2 on the PBS matrix along with the RD patterns exhibited of anatase form. In addition, the photocatalytic results showed that the capacity of black dye removal was 40%, 32% and 18% of 100 ADMI, 300 ADMI and 500 ADMI respectively.
