Photocatalytic degradation of endocrine disrupting compounds (EDCs) by using UV-LED light guide and immobilized nanotubular TiO2.

This study focuses on the development of a compact photocatalytic water treatment system with a new light source UV-LED light guide (UV-LLG) using immobilized TiO2. Immobilized TiO2 photocatalysts have been developed to overcome the limitations of powdered photocatalysts. Photocatalysts of 10 cm �� 10 cm size were prepared by anodic oxidation. SEM and XRD methodologies were analyzed to have self-growing nanotubes and anatase crystal structures. Using an energy-saving, space-saving UV-LLG, the treatment of new emerging contaminants, bisphenol A (BPA), 17��-ethinyl estradiol (EE2), and 17��- estradiol (E2), respectively, was removed. The results of comparing removal efficiency with light sources showed UV-LLG to be the most efficient, and energy and space saving.Maste
