Growth of boehmite nanofibers by assembling nanoparticles with surfactant micelles [PDF]

, 2004
It is known that boehmite (AlOOH) nanofibers formed in the presence of nonionic poly(ethylene oxide) (PEO) surfactant at 373 K. A novel approach is proposed in this study for the growth of the boehmite nanofibers: when fresh aluminum hydrate precipitate

Hydrothermal Synthesis of Hierarchical Boehmite from Co-Processed Stainless Steel Dust and Aluminum Dross Residue

Metals
Stainless steel dust and aluminum dross are large-volume solid wastes in the metallurgical industry. Synergistic treatment of these wastes recovers some metals but yields an Al-rich residue (Al2O3 > 50%) that represents both a resource loss and an ...

Dissolution of Phosphate in Mixed Fe- and Al-oxide Mineral Suspensions as Influenced by Reducing Conditions.

, 2005
The loss of soil phosphorus (P) to surface waters poses a threat to water quality. Research evaluating P dissolution and transfer among sorbents in pure mineral systems can provide basic knowledge useful for the environmental management of P.
