Abstract:

A method for the determination of bromate and perchlorate in drinking water was established by high performance liquid chromatography coupled to electrospray ionization quadrupole mass spectrometry (HPLC/ESI-MS). The chromatographic separation column used was a Waters XterraTM C18 column, and the binary mobile phase used consisted of acetonitrile as mobile phase A and 1.5 mmol/L aqueous solution of tetrabutyl ammonium hydroxide solution as mobile phase B. Both analytes were detected in the selected ion monitoring (SIM) mode. The developed calibration curve showed good linearity over the concentration range from 1 to 200 ng/mL. The detection limit was 1 ng/mL for both bromate and perchlorate.

Key words: bromate, perchlorate, drinking water, HPLC/ESI-MS
