WebUsing h-MoO3 macrorods as precursors in surfactant-assisted processes, gamma-Bi2MoO6 nanoplates with square laminar morphologies have been successfully synthesized by a facile hydrothermal method. The photodegradation efficiency of the as-prepared samples was investigated by monitoring the degradation of Rhodamine B and methylene blue … WebThe molybdenum blue method is based on the formation of Water sample collection and phosphomolybdate. At effective analytical preparation conditions, the amount of phosphates is About 50 mL of water samples …
WebThe triclinic phase of zinc molybdate α-ZnMoO4 (ZMO) was synthesized by a simple co-precipitation method at 600 °C. The crystal structure of the obtained polycrystalline sample of ZMO was characterized by X-ray diffraction (XRD) and Rietveld calculations using the space group P-1. WebInlerference in the phosphomolybdenum blue method comes primarily from As, Si and Ge, which also react with molybdate to form the corresponding isostructural acids which are reduced to heteropoly blues. All of these have absorption maxima close to each other (Figure 14.1). [Pg.1336]
WebUsing the molybdenum blue method we found that the classification of P into the traditional fractions (DIP, DOP, POP) applied in the ocean cannot be applied to turbid waters such as rivers because interferences between the fractions seems to occur. Therefore a new nomenclature has been introduced.
