| titleOfInvention | Method for photo-reduction of hexavalent chromium |
| abstract | The invention relates to a method for reducing hexavalent chromium ions in aqueous solution by adding a photo-initiation agent on the condition of illumination. The method includes the steps of adding the photo-initiation agent in the aqueous solution containing hexavalent chromium, adjusting the solution to be acidic, achieving reduction of hexavalent chromium after mixing on the condition of sunlight or artificial light illumination, and reducing highly toxic hexavalent chromium to be trivalent chromium with low toxicity and small solubility. The method is an economical, simple, fast, effective and environment-friendly method for reducing hexavalent chromium, greatly lowers reduction treatment cost of hexavalent chromium ions in aqueous solution, and is capable of achieving the purpose of harmless treatment of hexavalent chromium waste water. |
