Abstract
- Triclosan (TCS) is an antimicrobial agent used for personal care products that cannot be removed by wastewater treatment classical processes. TCS persistence and toxicity is asking for alternative treatment methods such as TiO 2 assisted photocatalyse. Due to the fact that within the literature are presented various pathways for TCS degradation via UV/TiO 2 photocatalysis, some data being contradictory, research work aimed to propose a degradation mechanism supported by as many experimental data. TCS degradation pathways confirmed by experimental results were: addition of hydroxyl radicals at TCS non-phenolic ring, proton extraction by hydroxyl radicals and direct interaction with photo generated electrons.
