Objectives: The purpose of this study was the investigation of bromide and bromate in drinking water of water supply plants, mineral springs and small water supply system located in northern area of Gyeonggi province.
Methods: Analytical method was based on EPA 326.0 to use Postcolumn reaction (PCR). The instrument was 887 professional UV/VIS detector IC manufactured in Metrohm.
Results: Bromate was detected at 0.5~2.4 μg/L in tap water from 5 water supply plants. These plants were used as disinfection method for sodium hypochlorite and on-site chlorine that causes generate bromate as a by products even if not used ozone.
Conclusions: The bromate was detected up to 2.5 μg/Lin drinking water in northern Gyeonggi area that showed within 10 μg/L for standard of tap water. However, the continuous monitoring of bromate is necessary in drinking water.
