PRECISE DETERMINATION OF PLUTONIUM BY DIFFERENTIAL SPECTROPHOTOMETRY
A method is described for the determination of milligram amounts of Pu by differential spectrophotometry with a precision ( sigma ) of plus or minus 0.05%. The sample is dissolved in HCl and maintained in the reduced state by the presence of hydroxylamine hydrochloride in the solution. The relative absorbancy of the sample is then measured against that of an accurately known standard solution at 5650 a. The optimum solution conditions to give highest precision have been selected and the effect of the presence of some foreign cations has been investigated. (auth)
