How to analyze the molybdate content containing MO3? Molybdate content is analyzed using spectrophotometry or gravimetry; how can the interference from MO3 be eliminated in this process? ? ? ? Because MO3 also participates in the reaction. Could some expert give me some guidance?
Molybdates are a large category; without specifying which molybdate salt it is, it is impossible to come up with clues for analysis. Theoretically, any cation that can bind with molybdate can form a molybdate, and there are numerous such cations.
Since you believe that sodium molybdate contains molybdenum trioxide, it means that some molybdate ions are not incorporated into salts. Try to analyze the sodium content accurately, and then calculate the amount of sodium molybdate present; the excess molybdenum corresponds to the equivalent of molybdenum trioxide.
