Abstract

A comparative study was made of the chromatographic behaviour of nine haloacetic acids, namely mono-, di-, and tri-fluoroacetate (MFA, DFA, and TFA, respectively); mono-, di-, and tri-chloroacetate (MCA, DCA, and TCA, respectively); and mono-, di- and tri-bromoacetate (MBA, DBA, and TBA, respectively), employing anion-exchange chromatography with suppressed conductivity and UV detection, using a Dionex AS17 anion-exchange column employed with a potassium hydroxide gradient (via a Dionex EG40 Eluent Generator). All nine haloacetic acids were completely separated under the optimized gradient elution conditions, and use of selective detection methods or pretreatment with an OnGuard II Ag cartridge resulted in the elimination of interferences from chloride and bromide occurring in soil samples. The procedure for the simultaneous determination of the nine haloacetic acids was simple and rapid. The method detection limits for MFA, DFA, TFA, MCA, DCA, TCA, MBA, DBA, and TBA were 21, 40, 40, 28, 48, 86, 67, 55, and 160 μg L⁻¹, respectively. Application of this method to the determination of haloacetic acids in real soil samples is illustrated.
