Some Observations on the Basic Chemistry of Plutonium,

Abstract

On prolonged heating in dilute nitric acid (0.5M to 6.8M) a considerable amount of Pu(+4) is oxidized to Pu(+8). Precipitation of the plus three plutonium oxalate is complete in fifteen minutes. Oxidation of Pu(+4) to Pu(+8) by bromine is quantitative at 105 deg C after 1/2 hour; at 50 deg C the rate of oxidation is slow, but measurable. At room temperature the rate is too slow to measure. A method of converting PuC13 to Pu(NO3)4 is given. A solubility of NaPuO2Ac3 increases with temperature the value at 25 deg C being 19.5 g/iiter and that at 95 deg C, 37.5 g/liter. Supersaturation was observed on slow cooling of a saturated solution. p2
