Abstract

Alumina modified bentonite is obtained by exchanging the medial-layer hydrated cation of bentonite by alumina polyoxoanion. The nature of alumina modified bentonite and that of non-modified bentonite are determined by such modern analytic methods as XRD, SEM, and BET. The alumina modified bentonite via alumina polyoxoanion has the layer-gap increase from 12.61 to 18Ǻ. The layer-gap and that of the medial layer of alumina modified bentonite are determined by the density of modified polyoxoanion, aging time of solution and OH-/Al3+ ratio. The OH/Al3+ratio of 2.0 is favorable for alumina modified bentonite via polyoxoanion. SEM images show that the medial-layer hydrated cation of bentonite has interacted with polyoxoanion during the operation.
