| Abstract: |
| Organic compounds in sodium aluminate solution will affect quality of alumina products and production in Bayer process. However, how to economically and efficiently remove organic compounds from sodium aluminate solution of Bayer process is still an industry problem to be solved. Origin, accumulation, hazard, and removal process of organic matters in Bayer were summarized. Application of simple and environment friendly technique of chemical oxidization in organic compounds degradation in Bayer process were discussed. Photochemical oxidization method was proposed to be a potential technique for organic compounds decomposition in Bayer process. |
