Abstract

This research aims to promote photocatalysis of endocrine disrupting chemicals (EDCs) in water. Two reactor setups with (i) modified air-clad optical fibres and (ii) waterproof LED strips were utilised to transmit light to photocatalysts P25 TiO₂ and gold-modified TiO₂ (Au-TiO₂). The performances to photodegrade 17α-ethynylestradiol (EE2) and estriol (E3) under Cool White and UVA high efficacy LEDs were examined. Au-TiO₂ showed superior photocatalytic activity for EE2 removal over P25 TiO₂. The pseudo first-order rate constants for EE2 photocatalysis under UVA were 0.55 h⁻¹ and 0.89 h⁻¹ for TiO₂ and Au-TiO₂, respectively. E3 was effectively degraded by Au-TiO₂ in the immersible LED strip reactor (0.13 h⁻¹).
