A spectrochemical method for the determination of boron in molybdenum was developed to aid in a metallurgical study on the effect of this element on the fabricability of molybdenum. Boron is determined in the 50 to 500 ppm range with a precision of ±10% using the 2496.78-A line. The range can be extended to 5 to 50 ppm and perhaps lower by using the 2497.73-A boron line and eliminating the filters that were used. The molybdenum is dissolved with hydrogen peroxide and the boron complexed with mannitol. Excitation is by low-amperage DC arc. The boron spectrum is enhanced by the use of sodium fluoride, and graphite is used to reduce the molybdenum spectrum. It is possible to use the technique for the determination of other impurities in molybdenum.
