A rapid and simple ion chromatographic (IC) method for the direct determination of bromide (Br-) in sea water was developed. A small amount of sea water was injected into a specific IC system where zwitterionic surfactants immobilized on octadecylsilica CODS) surfaces were used as the stationary pha
