An anion exchange resin (OH form) is converted to the chemiluminescent anion form with a new reagent N-(b-carboxypropionyl) isoluminol (CPIL). The anion of interest in the analyte solution displaces the reagent CPIL anion when passing through the resin, then reacts with a H2O2-Fe(CN)63- solution to produce luminescence. The intensity of the CL produced is linearly related to the concentration of the anion in the analyte solution A new flow injection chemiluminescence ion exchange technique is established, and can be used to determine Cl-, Br-, NO2-, NO3-, SO42- anions, with detection limits from 8.0 ?10-7 to 1.4 ?10-6 mol/dm-3, and linearity over two orders of magnitude.
Key words: BROMINE, SULFURIC ACID, CHLORINE, ANION-EXCHANGE RESINS, NITRIC ACID, FLOW INJECTION ANALYSIS, CHEMILUMINESSENCE, NITROUS ACID
