| titleOfInvention | Method for removing nonyl phenol through selective photocatalytic oxidation based on hydrophobic effect |
| abstract | The invention relates to a method for removing nonyl phenol by selective photocatalytic oxidation based on hydrophobic effect, which is characterized in that a hydrophobic titanium dioxide nanotube prepared by combining a three-step anodic oxidation method with a hydrophobic modification technology is used as a photocatalyst, a high-pressure xenon lamp is used as an excitation light source, and the nonyl phenol aqueous solution in a degradation tank is removed by photocatalytic oxidation under the condition of continuously pumping air into the degradation tank. Through hydrophobic modification on the surface of the catalyst, a perfluorinated silane hydrophobic layer is constructed on the surface, so that adsorption of hydrophobic pollutant nonyl phenol on the surface of the catalyst is enhanced, and the catalytic oxidation effect of the catalyst is promoted to be improved. Compared with a hydrophilic titanium dioxide nanotube catalyst, the hydrophobically modified titanium dioxide nanotube catalyst has a better degradation effect on nonyl phenol, the removal rate of nonyl phenol is about 100% in 40 minutes, and the removal efficiency is improved by about 15%; and hydrophilic pollutants coexisting in water have little influence on the oxidation removal efficiency of the nonyl phenol, so that good selective photocatalytic oxidation capability is embodied. |
