摘要：

The advantages of the bromide ion selective electrode in flow injection systems are pretty visible when analysing bromide in sea water at the average ratio of 1000. Br-/Cl- = 3.95, on 32-52 mg dm-3 bromide level. Direct flow injection potentiometry was applied without pretreating the sample. The matrix effect of high chloride concentration was simply removed while calibrating the electrode by means of sodium chloride. The results obtained agree well with those recommended in literature with coefficient of variation < 1% and the simplified system compares favourably with spectrophotometric methods.
