titleOfInvention | Method for enriching hexavalent chromium in water body through photochemical reaction |
abstract | The invention discloses a method for enriching hexavalent chromium in a water body through photochemical reaction, which belongs to the field of heavy metal wastewater treatment, and comprises the steps of mixing an electron donor with a water body containing Cr (VI), adjusting the pH value to 3.3-6.1 to form a mixed reaction liquid, and carrying out photochemical reaction on the mixed reaction liquid; the method has the advantages of few operation steps, simple operation and easy industrial application, and can directly mix and uniformly stir the prepared solution and carry out photochemical reaction after the pH is adjusted; the invention has low cost of raw materials and good reaction effect; the invention adopts homogeneous photochemical reaction, has no catalyst material, and the ligand is an alcohol substance with low price, thus being applicable to large-scale application; the method can remove heavy metal chromium ions in the water body, can separate out the chromium ions in a precipitation form, achieves the aim of enriching chromium, and can be used as a waste resource for recycling. |
