摘要: Abstract Photo-degradation of curcumin in the presence TiO 2 nanoparticles has been studied water–methanol and water–acetonitrile mixed solvents. Curcumin was found to form charge transfer (CT) complexes with nanoparticles. The binding constant CT determined. undergo photo-degradation under UV–vis only visible light irradiations. investigated external electron quenchers like methyl violegen dissolved oxygen hole iodide ions a de-aerated condition. enhance processes. be completely quenched both solvent mixtures A reaction pathway for proposed. This study successfully applied remove yellow turmeric stain from cotton fabrics.
