In this work, a rapid and easy capillary electrophoretic method for simultaneous determination of benzoic acid
and sorbic acid in food samples using direct UV detection was reported. The separation of acids was
achieved in fused silica capillary at 28 kV. 20 mM borate buffer at pH 9.3 was
used as running buffer; cinnamic acid was chosen as internal standard for
quantification. Under the optimal
separation conditions benzoic acid and sorbic acid were detected in 3.1 min.
The linear ranges were between 0.005-0.4 mM. The correlation coefficients for
each calibration curve were calculated as 0.999. The reproducibility of peak
area and migration time for each acid were less than 3% (R.S.D.). The limits of
detection were found 0.405 mg/mL for
benzoic acid and 0.415 mg/mL for sorbic acid. The limits of
quantification were 1.35 μg/mL
and 1.38 μg/mL respectively.
