Photocatalytic degrad ation of n onionic s urfactant from wast ewater us ing Zinc ox ide nanoparticles

During surfactant production and text ile manufacturing pro cesses a large amount of waste water with toxicity ca n be introduced into aquatic syst ems [۱]. In recent years analtern ative to con ventional methods, is “a dvanced oxidation proc esses” (AOPs), based o n the gener ation of ver y reactive s pecies such as hydroxyl radicals, th at oxidizes a broad range of organic pollutants quickly and non-selectively. AOPs include pho tocatalysis systems such as a combination of a semiconductor (TiO۲, ZnO, etc.) and UV li ght [۲]. In our researc h, we select ed a nonionic surfact ant as a m odel compound for o rganic pollutants and ZnO nanoparticles as photocatalyst. The effects of various parameters, such as the concentration of the ph otocatalyst, illumination time, electron acceptor, initial concentration and pH o f the reacti on on photo catalytic degradation of NP۱۰EO we re studied.
