| Abstract: | Cathodic stripping voltammetry is evaluated for the simultaneous determination of chloride, bromide and iodide in mixtures. Results are similar to those obtained with ion-selective electrodes. Detection limits are 177 μg l?1 for chloride, 40 μg l?1 for bromide, and 8 μg l?1 for iodide. Dam water and human spinal fluid were analyzed satisfactorily. |
