Resumo
Neutron activation analysis (NAA) for Al
determination in tree bark samples containing phosphorus
and silicon was studied. The contributions of the
31P(n,a)28Al and 28Si(n,p)28Al reactions to the
27Al(n,c)28Al reaction were corrected determining interference
correction factors. Analytical quality control was
evaluated by analyzing certified reference materials. The
results presented good accuracy and precision. Replicate Al
determinations in bark samples showed relative standard
deviations ranging from 4.2 to 10.5%. The detection limits
were lower than the mass fractions found in the samples,
demonstrating the possibility to apply NAA in Al determinations
in tree barks for biomonitoring studies and
purposes.
