Abstract

The determination of oxygen in lead by3He and4He activation analysis was studied. Both methods were applied to the same material containing 0.9 μg·g−1 of oxygen. The18F formed from oxygen was separated from matrix activities by extraction of Po with N-benzoyl-N-fenylhydroxylamine, followed by distillation of fluorosilicic acid and precipitation of lead fluorochloride (4He activation) or by distillation followed by precipitation (3He activation). The yield of the separation, which amounted on the average to 68%, was determined via the19F(n,4He)16N reaction. The coefficients of variation were 21 and 45% for4He and3He activation analysis, respectively, thus indicating a less homogeneous distribution of the oxygen. Nuclear interferences of sodium and fluorine were shown to be negligible.
