Abstract
A novel microemulsion electrokinetic chromatography with photo diode array detection method was developed for separation and determination of 2-methoxybenzoic acid, 2-chlorobenzoic acid and 2-hydroxybenzoic acid. Under the conditions of microemulsion 10 % (v/v), Na2B4O7 20 mmol/L, pH 10.10 and separation voltage 12 kV, the separation was achieved. Good linear relationships between peak height and concentration were found in the tested range. Relative standard deviations (n = 5) of migration times and peak heights were less than 1.95 and 3.26 %, respectively. The detection limits for 2-methoxybenzoic acid, 2-chlorobenzoic acid and 2-hydroxybenzoic acid were 14.1, 7.46 and 10.0 ng/L, respectively. The method was applied for the determination of the three compounds in lab waste water with recoveries of 94.2-112.4 %.
