| titleOfInvention | A method for photocatalytic reduction of hexavalent chromium in a wide pH range using ultrathin Bi24O31Br10 nanosheets |
| abstract | The invention belongs to the technical field of environmental protection, in particular to a method for removing hexavalent chromium in a wide pH range by photocatalytic reduction of ultrathin Bi 24 O 31 Br 10 nanosheets. The method includes the following steps: (1) preparing an ultrathin Bi 24 O 31 Br 10 nanosheet photocatalyst; (2) adding the synthesized visible light photocatalyst to solutions containing 30 mg/L hexavalent chromium at different pH; (3) turning on Magnetic stirrer, dark adsorption for 1 h to allow hexavalent chromium to reach adsorption equilibrium on the synthesized ultra-thin Bi 24 O 31 Br 10 nanosheets with Bi vacancies; (4) Use a 300W xenon lamp with a 420 nm filter as the visible light source, turn on the light source The hexavalent chromium-containing solution is subjected to illumination treatment; (5) after the illumination reaction is completed, the precipitation supernatant is discharged, and the photocatalytic material naturally settled in the sedimentation tank is recovered and returned to the photocatalytic reaction tank. The invention utilizes the ultra-thin Bi 24 O 31 Br 10 nano-sheet photocatalyst to realize the efficient photocatalytic reduction and removal of hexavalent chromium in a wide pH range, and has the advantages of simple process, energy saving and high efficiency, no secondary pollution and strong resistance to pH fluctuations.
