Abstract: | The indirect determination of chloride in water is based on measurement of the difference in conductivity after the sample has passed through ion-exchange columns in the hydrogen form and silver form. The linear response range is about 0.5–10 μg g?1 chloride (with 3 μg g?1 nitrate and 5 μg g?1 sulfate); the detection limit is about 50 ng g?1 chloride but depends strongly on the concentrations of other anions. |
