The method accuracy for analyse of vinegar was not confirmed
using a certified reference material because there is no certified
reference material for vinegar. However, a certified reference
material of bovine liver furnished by the National Institute of Standard
and Technology was analysed, which has certified value for
cadmium of (0.50 ± 0.03 lg g1
). Using the proposed method was
found cadmium content of (0.48 ± 0.03 lg g1
).
