A simple method for the determination of total bromide in foods was investigated.A 10g sample was ashed with magnesium oxide and dissolved in water. After centri-fugation, the solution was oxidized with potassium dichromate sulfuric acid mixture in a bromine generator.The liberated bromine was reacted with fluroescein and quantitated by measurement of the absorbance at 505 nm. Chlorine ion did not interfere at up to 1200 fold excess. Iodine ion could be eliminated before the assay by bubbling nitrogen through the solution under mild oxidizing conditions. This method can determine as little as 0.1 ppm of bromine in a sample. The recoveries of bromide were 91-100%, the precision (CV%) were 0.7-7.7. With this method, the determination result of bromide in NBS standard reference material was agreed with it's reference value.
