ANALYTICAL METHOD FOR THE ABSORPTIOMETRIC DETERMINATION OF BORON IN SODIUM METAL

Technical Report ·
OSTI ID:4736973
Sodium metal is dissolved in water under an inert atmosphere of argon, and the resulting sodium hydroxide solution is evaporated to dryness. Rosocyanin is formed, separated from excess curcumin, and dissolved in ethanol for absorptiometric measurement. The method is applicable to sodium metal containing 0.1 to 1 ppm boron. The precision should be within plus or minus 20% (95% confidence limits) at the 0.5 ppm boron level. (auth)
