Time Required

Stable and relatively concentrated aqueous suspensions of nano-sized stoichiometric hydroxyapatite could be prepared by a precipitation method in the presence of suitable surface active agent (SAA). The method includes the precipitation, vacuum filtration and washing of the precipitated powders, followed by re-dispersion. It could be concluded that the added amount of the SAA should be enough to cover the primary particles surface, and that washing should be better carried out using a SAA solution. The method developed enables the precipitation of the powders and the preparation of suspensions, while significantly shortening the overall time required for colloidal processing consuming.

Uva Irradiation

The TiO2-calcium phosphate (TiO2/CP) nanocomposites with different ratios were prepared by precipitation of calcium phosphate in the presence of nano-sized TiO2. The products were characterized by BET, XRD, SEM and EDX techniques. Photocatalytic activity of the nanocomposites was evaluated as a rate constant of decomposition reaction of methylene blue (MB) in aqueous suspensions under UVA irradiation. It was observed that all of the nanocomposites showed higher photocatalytic activity in comparison to pure TiO2 catalyst. In particular, the rate constant photodecomposition of MB on TiO2/CP composite at 9:1 ratio (w/w) was above five times higher than on pure TiO2.
