Abstract  

The study was undertaken to determine the immunity of the Pu(III) spectrophotometric assay to diverse species. We acquired spectra of a set of solutions containing 10 mM Pu(III), reduced with ascorbic acid-aminoguanidine in 2M HCl, and of a similar set of solutions containing a spike of test species. The initial molar ratio of plutonium to species was 101, and after interference it was increased to 100.1, etc., until no interference occurred. The species examined were element numbers 1, 9, 11–13, 17, 19, 22–31, 35, 42, 44–46, 48, 50, 53, 57, 58, 60, 62, 73, 74, 76, 77, 79, 83, 90, 92, 93, 95 and nitrate, phosphate, sulfate, and oxalic acid.
