摘要
拜耳法铝酸钠溶液中的有机物将影响氧化铝产品质量、生产顺行,而如何经济、高效地对拜耳法铝酸钠溶液中有机物进行脱除至今仍是亟待解决的行业难题。综述了拜耳法铝酸钠中有机物的来源、积累、危害及其脱除的研究进展,重点分析了工艺简单、清洁环保的化学氧化技术用于拜耳法铝酸钠溶液中有机物脱除的研究现状,并对光—化学催化氧化技术在铝酸钠溶液中有机物的脱除进行了展望。
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.
