GB/T 5195.6-2006 Fluorspar—Determination of phosphorus content

Scope

This standard specifies the principles, reagents, instruments, samples, analytical procedures, calculation of analytical results, and allowable deviations for determining the phosphorus content in fluorite. This standard includes two methods: the molybdenum blue spectrophotometry, with a measurement range (mass fraction expressed as P): 0.002% to 0.50%; and the ammonium phosphomolybdate reduction spectrophotometry, with a measurement range (mass fraction expressed as P): 0.001% to 0.30%. This standard is applicable to the determination of phosphorus content in fluorite.
