This work demonstrates significant sodium dodecylbenzenesulfonate degradation in wastewater, indicating enhanced visible-light photocatlaytic efficiency using iron rust-derived photocatalyst.
Anionic surfactant in wastewater poses serious environmental risks, and conventional treatment methods often fail to degrade them completely. Titanium dioxide (TiO 2 ) is a widespread photocatalyst, but its limited efficiency under visible light remains a challenge. While Fe doping and magnetic functionalization enhance TiO 2 photocatalysis, existing methods rely on costly and high-purity reagents. This study introduces a sustainable approach by repurposing iron rust waste to synthesize Fe-doped and Fe 3 O 4 -magnetized TiO 2 (TiO 2 -Fe/Fe 3 O 4 ) via hydrothermal Fe doping and Fe 3 O 4 magnetization through co-precipitation. The photocatalysts were tested for anionic surfactant of sodium dodecylbenzenesulfonate (SDBS) degradation under varying conditions. TiO 2 -Fe/Fe 3 O 4 achieved 93.26% SDBS degradation under visible light at pH 6, with 0.5 g/L photocatalyst and 60 min of irradiation. This study successfully utilized iron rust waste to convert into beneficial material in enhancing the TiO 2 that can be magnetically recovered and visible-light-activated. These dual benefits of increased photocatalytic efficiency and easy separation provide a cost-effective as well as eco-friendly solution for surfactant degradation in wastewater treatment.
