The iodimetric titration method for the determination of bromide involves the observation of various color changes, making the method unsuitable for use with samples that are highly colored. A modification is described, which extends the usefulness of the method to highly colored samples, such as sewage and industrial waste effluents. The obvious substitution of a pH meter for indicators was made and the use of standardized concentrations and amounts of reagents added was incorporated into the method. The procedural steps were studied in order to optimize the sensitivity while minimizing interfering side reactions. The modified method was applied to a mixed domestic-industrial waste effluent spiked with bromide and iodide. The experimental details and statistical parameters for samples spiked at different levels are presented.
