Preparation of Aluminum Phosphate Catalysts Using Various Aluminum Salts

Al-containing acidic and basic sodium aluminum phosphate preparation and use in studies of oral aluminum bioavailability from foods utilizing Al as an aluminum tracer

We synthesized Al-containing acidic and basic (alkaline) sodium aluminum phosphates (SALPs) which are FDAapproved leavening and emulsifying agents, respectively, and used them to determine the oral bioavailability of aluminum incorporated in selected foods. We selected applicable methods from published syntheses (patents) and scaled them down ( 3000and 850-fold) to prepare 300–400 mg of each SA...

Formation of Aluminum Hydroxides as Influenced by Aluminum Salts and Bases

-The influence of different ions in the formation of AI(OH)3 polymorphs has been studied experimentally by promoting stoichiometric reactions between the aluminum salts (A1C13, Al(NO3)3, A12(504)3) and bases (NaOH, KOH, NH4OH). In all cases the polymorphs obtained were a mixture of gibbsite, bayerite and nordstrandite or pseudoboehmite with the exception of the reaction between KOH, or NH4OH an...

Preparation of Γ-alumina from Aluminum Aminoalkoxides

The synthesis of materials with tailored properties is one of the most active areas of material science [1, 2]. Among so many materials, γ-alumina due to the significant application in catalysis, electronic and ceramic industry has been studied extensively [3]. Various processes have been employed for the preparation of high quality alumina, including sol-gel processing from aluminum alkoxides....

Accumulation and Depletion of Aluminum from Various Tissues of Rats Following Aluminum Citrate Ingestion

Preparation of polymeric phosphate aluminum-ferric chloride (PPAFC) and its application in humic acid removal

Polymeric phosphate aluminum-ferric chloride (PPAFC) in this study was prepared. In order to obtain the optimum conditions for preparation of PPAFC, resulting in a better turbidity removal efficiency, parameters such as the molar ratio of Al/Fe, P/(Al+Fe), OH/(Al+Fe) as well as the reaction temperature were examined. Results showed that the optimal synthetic conditions were Al/Fe of 6:4, P/(Al+...
