Abstract:

Aminobenzoic acids are of major interest in clin. anal., but their detn. in environmental samples has been rarely done. Therefore a method for the detn. of 10 aminobenzoic acids in water has been developed, using high-performance liq. chromatog. with combined diode array and fluorescence detection. Sepn. of the analytes has been achieved with a buffer pH 3/methanol gradient. The general elution order has been m-substituted <p-subst. <o-subst. aminobenzoic acids. UV and fluorescence data are presented. In a highly polluted water sample of the former ammunition plant Stadtallendorf/Hessen, 4-aminobenzoic acid, 2-aminobenzoic acid and 2-amino-4-nitrobenzoic acid have been detected. After passing a charcoal filter, only the concn. of 4-aminobenzoic acid in a sample from the same site has been above the detection limit. Besides the ten analytes investigated, several unknown compds. have been present in the samples.
