Chemistry and Structure of Al(Oh)/Organic Precipitates - A Small-Angle X-Ray-Scattering Study .2. Speciation and Structure of the Aggregates
The fitting of experimental SAXS curves of Al/organics suspensions by synthetic curves allowed the determination of the Al speciation within the precipitates. The simulations showed that the subunits of the precipitates are mainly uncondensed monomers, which partly originate from the depolymerization of Ails. The precipitates are built by dense aggregation of uncondensed monomers (log I(Q)-log Q slope > -2.3), formation of dense-Al(OH)Al- colloids, and loose linear aggregates of oligomers.
