Summary:Adsorption and photocatalytic degradation of aerobically-treated palm oil mill effluent (AT-POME), a prominent effluent across palm oil producing countries, using commercially available TiO2 P25 Degussa powder and titania nanotubes (TNT) prepared via hydrothermal technique was investigated. The as-prepared TNT exhibited tubular, open ended structure, unchanged crystallinity as compared to TiO2 and a surface area close to 200 m2/g, almost 4 folds as compared to commercial TiO2. TNT outperformed TiO2 in terms of adsorption and photodegradation of AT-POME under ultraviolet (UV) light irradiation, where TNT was able to remove up to 81% of AT-POME coloration as opposed to commercial TiO2 (69.5%) within the same experiment duration. The results indicate that TNT performs better compared to commercial TiO2 for wastewater remediation via photocatalysis.
