Mechanisms of chromate adsorption on boehmite
Journal of Hazardous Materials, 2015Adsorption reactions play an important role in the transport behavior of groundwater contaminants. Molecular-scale information is needed to elucidate the mechanisms by which ions coordinate to soil mineral surfaces. In this study, we characterized the mechanisms of chromate adsorption on boehmite (γ-AlOOH) using a combination of extended X-ray ...

Vacuum dehydration of boehmite
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19591. The vacuum dehydration of boehmite at low temperatures gives homogeneously porous preparations of high specific surface (about 300 sq. m/g and higher) with preservation of the crystal structure. 2. The specific surfaces of vacuum-dehydration products are independent of temperature in the range 20–420°.

The Crystal Structure of Boehmite
Clays and Clay Minerals, 1979AbstractThe crystal structure of a synthetic boehmite sample has been refined to an R of 0.047 in the space group Amam from X-ray powder diffraction data. Inclusion of hydrogen atoms and/or refinement in the space group A21am gave poorer results. Cell dimensions were determined as a = 3.6936 (± 0.0003), b = 12.214 (± 0.001), c = 2.8679 (± 0.0003) Å ...
