- Technological University of Sofia, Department of Analytical Chemistry, 8 Kliment Ohridski Str., 1756 Sofia, Bulgaria Anorganisch Chemisches Institut, Der Westfilischen Wilhelms universitat, Wilhelm Klemmstr 8, D-4400, Münster, BRD Manuscript received 18 June 1990, revised 4 February 1991, accepted 20 March 1991 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-/C1-=3.95 on 32 —52 mg dm-1 bromide level Direct flow injection potentio. metry 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
