Abstract
The determination of boron, carbon, nitrogen and oxygen in nickel by charged particle activation using the reactions 10B(d, n)11C, 12C(d, n)13N, 14N(p, α)11C and 16O(3He, p)18F is studied. The interference of 11B(p, n)11C with the 14N(p, α)11C reaction is taken into account. 11C, 13N and 18F are separated by oxygen combustion followed by trapping of 11CO2 in NaOH and by steam distillation of 13NH3 and of H2Si18F6, respectively. The results obtained were 0.129±0.035 μg g−1 for boron, 86.4±8.3 μg g−1 for carbon, 1.077±0.037 μg g−1 for nitrogen and 8.91±1.00 μg g−1 for oxygen. The results for nitrogen and oxygen agreed satisfactorily with those of other analytical methods.
