Abstract

A spectrophotometric method was developed for the analysis of bromate in drinking water. This method requires no sample preconcentration and involves reaction with acidified fuchsin and absorbance measurements at 547 nm. Bromate is detected above 5 µg/L concentration and quantified with the linear range of 50 to 200 µg/L calibration solutions. Drinking water samples in Metro Manila were determined to have high bromate levels, ranging from 17 to 411 µg/L. Bromate, a probable carcinogen, has water quality guideline values of 10 µg/L and 25 µg/L set by the U.S. Environment Protection Agency and the World Health Organization, respectively, as maximum allowable contaminant levels.
