摘要: Alumina refiners have been aware of some the potential uses Layered Double Hydroxides (LDH’s) in Bayer process for more than a decade. By virtue their lamellar structure, ability to adjust separation these layers, and reactivity interlayer region, LDH’s can be used controlled addition or removal variety species, both organic inorganic. In this paper, we review history present use alumina refining, particularly most commonly calcium magnesium aluminate varieties.
