✦ Synopsis

Chitosan-modified carbon glassy electrode (CMGCE) was used for the determination of Br 7 for the first time. The measurement was carried out by cathodic stripping voltammetry. The effects of several experimental parameters, such as pH, the amount of modifier, deposition potential, deposition time were studied for analytical application. We also studied the adsorption isothermal line of bromide. A linear response was obtained in the concentration range 3.2610 76 -6.4610 75 g=mL of Br 7 . The detection limit was found to be 9.6610 77 g=mL. The method was used to detect bromide content in cetytrimethylammonium bromide (CTMAB), tetrabutyl ammonium bromide (TAB) and wastewater, the results are satisfactory.
