✦ Synopsis

High-performance liquid chromatography on a Zipax SAX column with U.V. detection at 200 nm gives precise results for bromide. Chloride, bromate, nitrite, nitrate, iodide, thiocyanate and various cations do not interfere; prior treatment with activated charcoal removes interfering organic compounds. Calibration graphs are linear over the range O-50 mg 1-l bromide in aqueous extracts of the particulates; the limit of detection is 10 ng of bromide.

The relative standard deviations at the 0.5 and 1.0 mg 1-l levels are 2.3 and l.O%, respectively.
