An estimation was made of the amount of Pu(III) and Pu(IV) present in the IBP stream in the Redox process. This work was undentaken in order to establish an analytical method suitable for routine control analysis. A procedure based on carrying of Pu(IV) upon a Zr phenylarsonate precipitate has proven satisfactory. The method employed and analytical results obtained from known solutions are described. An average recovery of 98.5% on Pu(III) and 97.7% on Pu(IV) was obtained from 50-50 mixtures. The standard deviation for individual results was 1.7%. When the Pu(III) to Pu(IV) raiio is five, similar results are obtained. However, as the Pu(III) to Pu(IV) ratio decreases, the accuracy of the method also decreases. From the data obtained, it appears that the Zr phenylarsonate method should be satisfactory for analysis for Pu(III) and Pu(IV) in the IBP stream. It should be noted thnt the method is applicable only under a limited set of conditions and the degree of accuracy obtainable should be taken into full consideration when reporting results. (auth)
