Adsorption behavior of condensed phosphate on aluminum hydroxide.
Sodium pyrophosphate (pyro-P, Na4P2O7), sodium tripolyphosphate (tripoly-P, Na5P3O10), and sodium hexametaphosphate (meta-P, (NaPO3)6) were selected as the model compounds of condensed phosphate to investigate the adsorption behavior of condensed phosphate on aluminum hydroxide. The adsorption was found to be endothermic and divisible into two stages: (1) fast adsorption within 1 h; and (2) slo...

متن کاملSolid State NMR Studies of the Aluminum Hydride Phases
Several solid state NMR techniques including magic-angle-spinning (MAS) and multiple-quantum (MQ) MAS experiments have been used to characterize various AlH3 samples. MAS-NMR spectra for the H and Al nuclei have been obtained on a variety of AlH3 samples that include the βand γ-phases as well as the most stable α-phase. While the dominant components in these NMR spectra correspond to the alumin...
متن کاملComparison of Adsorption of Phosphate, Tartrate, and Oxalate on Hydroxy Aluminum Montmorillonite Complexes
-Competitive adsorption between phosphate, tartrate and oxalate was studied on two hydroxy aluminum montmorillonite complexes (A1Mtl.6 and AIMt6), which were prepared by adding a base to pH 5.5 to samples containing 1.6 and 6.0 mol AI per kg clay. The quantities of phosphate, tartrate and oxalate adsorbed were more closely related to the amount of OH-AI species coatings on the montmorillonite t...
متن کاملNonequivalence of the metal binding sites of conalbumin. Calorimetric and spectrophotometric studies of aluminum binding.
Differential scanning calorimetric experiments show that addition of Al(III) to conalbumin increases its denaturation temperature by 5 degrees, from 60 to 68 degrees. Only one Al(III) bound per conalbumin molecule produces this change in heat stability; additional bound Al(III) does not affect the heat stability. Since Al(III) displaces both Cu(II) bound at the metal binding sites of conalbumin...
