Abstract
This study was performed to compare international analytical methods of bromide and applied to determine bromide in bottled mineral water and raw ground water in Korea. Bromide in water was eluted by 10~50 mM potassium hydroxide (KOH) and determined by ion chromatography-suppressed conductivity detector (IC-CD). Sample was purified with Ba- and H-on-guard cartridge and 0.2 μm membrane filter. The method detection limit (MDL) and the limit of quantitation (LOQ) of bromide were 0.2 and 0.5 μg/L, respectively. The calibration curve showed good lineality above 0.9993 in the ranges of the 0.5~80 μg/L. A correlation coefficient of bromide in ground water and sum of bromide and bromate in bottled mineral water is 0.808.
