Ferguson, W S; Newell, D M

A titrimetric method for the determination of fluoride in plutonium is reported. Prior to a steam distillation of the fluoride, the bulk of the plutonium is separated by precipitation of the sulfate. The fluoride in the distillate is titrated at a pH of 3.2 with 0.001M thorium nitrate using chrome azurol-S indicator. Applied to samples containing 1 to 15 parts per million fluoride, the recovery is 87%, and the precision on the 95% confidence level is plus or minus 0.65 ppm. (auth)
