A fast and sensitive direct chemiluminescence flow injection procedure for determination of humic acid in natural waters was developed and applied to water from the Czarna River, near Biaystok, Poland. N-bromosuccinimide (NBS) after on-line hydrolysis was used as a reagent evolving chemiluminescence by the oxidation of humic acid. Use of glycine as a sensitizer enhances the signal magnitude approximately 100 times.
