| titleOfInvention | Method for synchronously removing low-concentration citric acid complex copper and hexavalent chromium in wastewater and application thereof |
| abstract | The invention provides a method for synchronously removing low-concentration citric acid complex copper and hexavalent chromium in wastewater and application thereof, wherein the method comprises the following steps: treating wastewater containing citric acid complex copper and hexavalent chromium by ultraviolet irradiation, adding alkali for precipitation, and separating. Compared with the prior art, the invention has the advantages that the UV/Cu II (Cit), pyruvic acid and CO are finally formed 2 ·‑ Free radicals, which realize efficient reduction of Cr (VI), so that chromium ions mainly exist in the form of Cr (III) in the solution; for Cu II (Cit) copper ion, UV/Cu on the one hand II (Cit) the breaking action of HO & free radicals generated in the system; on the other hand, Cu is generated under the condition of UV radiation II The generated LMCT effect in the (Cit) structure and the final alkali precipitation can realize the Cu 2+ And cr (iii) are removed efficiently. The invention realizes the simultaneous removal of the copper and chromium double metals, and has simple method and low cost. |
