Abstract
A spectrophotometric method for measuring the chemical yield in radioc hemical neutron activation analysis of selenium in feedstuffs and biol ogical materials is described. The method is based on measuring the ab sorbance at 350 nm, which is due to the 5-nitro-2,1,3-benzoselenadiazo le complex formed between selenium and 4-nitro-1,2-diaminobenzene. The technique was checked against radiotracer techniques using Se-75 or S e-81m, and was illustrated by results for different botanical samples and certified reference materials.
