Greener Method for the Application of TiO2 Nanoparticles to Remove Herbicide in Water

TiO2 nanoparticles have emerged as a great photocatalyst to degrade organic contaminants in water; however, the dispersed water could be difficult recovered and potentially become contaminant. Herbicide like 2,4-dichlorophenoxyacetic acid (2,4-D) used agriculture usually ends up with large fraction remaining sediment, which may cause potential risk human health ecosystem. This study proposes greener method utilize remove 2,4-D from water. Accordingly, (10–45 nm) were synthesized grafted on lightweight fired clay generate TiO2-based floating photocatalyst. Experimental testing revealed that 60.2% of (0.1 mM) can decomposed 250 min under UV light TiO2-grafted Degradation fits well into pseudo-first-order kinetic model. The photocatalysts approximately 50% sunlight degradation efficiency is stable for cycles. results fabrication promising way herbicide using TiO2.
