REMOVAL OF TRIBUTYL PHOSPHATE FROM AQUEOUS SOLUTIONS BY TiO2 HETEROGENEOUS PHOTOCATALYSIS SUPPORTED OVER A NEW METAL PLATE WITH KINETIC STUDY

Abstract The aim of this investigation was to study the degradation of tributyl phosphate (TBP) in aqueous solution by heterogeneous photocatalysis (UV-C/TiO2). To perform the investigation, aqueous solutions containing the contaminant were exposed to UV radiation in the absence or presence of TiO2 in suspension or supported on a Fe-Cr metal alloy plate. TBP analyses before and after the treatment were performed by Ultra-Performance Liquid Chromatography (UPLC) in order to quantify the contaminant degradation. The results showed that the TiO2 photocatalytic system was able to remove TBP from t...
