GSC colorimetry: Mo, W
Geological Survey of Canada, colorimetry using dithiol, to determine Mo, W, sodium carbonate + sodium chloride + potassium nitrate fusion
The sample is fused with a mixture of sodium carbonate, sodium chloride and potassium nitrate. The test solution is split into two parts, to allow for the separate determinations of molybdenum and tungsten. Dithiol is used as the colorimetric reagent.
The technique was described by North in 1956 and is clearly explained by Stanton (1966).
