  • Method for generating hydroxyl radical and removing organic pollutants in water by utilizing an organic membrane
    Patent number: 10364165
    Abstract: The present invention provides a method for generating hydroxyl radicals and removing organic pollutants in water by utilizing an organic membrane. The inventive method generates hydroxyl radicals by adopting a nitrocellulose membrane as a photocatalytic material, placing the nitrocellulose membrane in water, illuminating with the sun or a sunlamp having a wavelength above 280 nm as a light source, and causing the nitrocellulose membrane to undergo a photochemical reaction at the membrane surface, and the generation rate of hydroxyl radicals can be achieved by adjusting the surface area of the membrane and a light intensity. The generated hydroxyl radicals can remove phenol, bisphenol A, thiamphenicol and other typical organic pollutants in water very well.
