| titleOfInvention | Method for recovering elemental sulfur by photoinduced catalytic disproportionation of sulfur dioxide absorption liquid |
| abstract | The invention discloses a method for recovering elemental sulfur by sulfur dioxide absorption liquid through photoinduced catalytic disproportionation, which comprises the steps of carrying out disproportionation reaction on the sulfur dioxide absorption liquid under the conditions of illumination and iodine ion catalysis to generate elemental sulfur precipitate; the method can be carried out under normal temperature and pressure, and has the advantages of low energy consumption and sulfur hardening prevention compared with the traditional high-temperature method; the method has the advantages of easy recovery of elemental sulfur, short flow, simple operation, no secondary pollution and contribution to industrial application. |
