Spectrophotometry Determination of Silicate with Molybdenum Blue. The amount of silicate in the PBS samples was determined using molybdenum blue chemistry [18,19], which is illustrated in Figure 4.
After reacting the sample 10 minutes with oxalic acid, 0.5 mL of 2% ascorbic acid (Acros Organics) was added to reduce the silicomolybdic acid to the molybdenum blue complex.
In this work, the influence of synthesis and experimental parameters on the morphology and biodegradability of MSNPs was investigated by means of an optimized molybdenum blue chemistry and spectrophotometric analysis.
Broth P was determined by Molybdenum blue method .
The amount of soluble P released in the NBRIP broth by each of the 16 isolates was quantitatively measured by Molybdenum Blue method describes by Watanabe and Olsen in 1965.
The enzymatic reduction of molybdenum is molybdenum blue a colloid that does not pass through dialysis tubing.

After that, phosphomolybdate complex reduced to molybdenum blue
, which can be measured colorimetrically at wavelength near 700 nm.
Soluble phosphorus was determined via formation of molybdenum blue by reacting with ammonium molybdate, [([NH.sub.4]).sub.6][Mo.sub.7][O.sub.24], and stannous chloride, Sn[Cl.sub.2], to form the brightly blue-colored heteropoly-molybdenum blue (Wei and others 2009).
The effect of low-molecular-weight organic acids and inorganic phosphorus concentration on the determination of soil phosphorus by the molybdenum blue reaction.
Phosphorus in the soil extracts is usually measured colourimetrically, most commonly by the molybdenum blue method of Murphy and Riley (1962).
It is generally considered that analysis by ICP measures organic forms of P that may not be measured by the molybdenum blue method, which measures predominantly orthophosphate.
