查询词典 phosphomolybdate

Bismuth phosphomolybdate is a catalyst in the production of acrylonitrile, an important raw material for fibres and plastics.

In the medium of 0.013 mol/L H2SO4, phosphate reacts with sodium molybdate and potassium antimonyl tartrate, forming a yellowish phosphorus-antimony-molybdenum heteropoly acid. The acid exhibited a strong resonance scattering peak at 710 nm after added with nanogold. The heteropoly acid was reduced by ascorbic acid to antimony phosphomolybdate blue, which caused the decrease of resonance scattering intensity.
