Abstract: The present work reports the results from the photocatalytic decomposition of gelatine factories wastewater by using anatase TiO2 particles prepared onto surface of glass materials. An experimental method adapted from emulsion templating approach associated with sol-gel process was employed to prepare and for fixing the catalyst. The resulting material was characterized by X-ray diffraction (XRD), Raman spectroscopy, Scanning electronic microscopy (SEM), and X-Ray fluorescence. The developed material was applied in gelatine factories wastewater remediation by photocatalytic process assisted by TiO 2 and UV irradiation. The efficiency for substrate mineralization was analysed by the total organic carbon (TOC) reduction in the effluent. Experiments were conducted in a cylindrical Pyrex reactor of 250 mL capacity. A 125 w Phillips medium pressure mercury lamp was used as light source (113.4 Jm2 s-1). The toxicity assay was evaluated and the TOC reduction reached values around 90%.
