10 μg Sb L−1 and the results are the average of threemeasurements. No
enhancing effects were observed for the 14 elements tested. On the
other hand, Bi, Cr, Sn and V produced signal depression of the analyte
when both substrates were tested. In all cases depressions of Sb signal
b20% were observed. Based on the data obtained in this study, it is not
possible to choose the most suitable substrate in terms of interference
control because the results are similar
