Abstract An extractive flow injection analysis for rapid, sensitive and selective determination
of perchlorate by spectrophotometric detection is proposed. The method is based on the
extraction of perchlorate with Brilliant Cresyl Blue on methyl isobutyl ketone at pH 6.0.
Perchlorate can be determined in the range of 0.008-1.00 μg/ml with a limit of detection of
0.003 μg/ml and rate of 30±5 samples/h. The effects of reagent concentration, pH, manifold
variables and diverse ions are completely studied. The usefulness of the method was ...
