Abstract: | Spectrophotometric studies have been used to determine the optimal formation conditions and stoichiometry of the reduced molybdoantimonylphosphoric acid. It was found that a [H+]/[MoO2-4] ratio of70± 10 was optimal for formation between 0.0008 and 0.01 M molybdenum. This corresponds to solution conditions that favor the existence of the dimeric form of molybdenum. The [H+]/[MoO2-4] criteria allows simple variation of experimental conditions. The stoichiometry of the reduced heteropoly acid was surmised to be PSb2Mo10O40 from spectral studies and elemental analysis. |
