| Abstract: | The phosphorus in leaching solution of the black tungsten ore is determined by ammonium vanadate-molybdate spectrophotometry. The effects of determined the wave length, the reagent dosage, the colored time and the temperature on absorbency were investigated. The molar absorptivity is 2.0×10^4L·mol^-1·cm^-1 at its biggest absorption wave length of 315 nm.The volume of colorant solution is 0.6 mL. Beer＇ s law is obeyed in the range of 0.64-3.2μg/mL for arsenic. The colored time is 10 min. The recovery ratio is 100.4%, the relative standard deviation RSD is 1.01%. The sensitivity is high, the operation is simple, and so the method has met the requirement for determining leaching solution of the black tungsten ore. |
