| Abstract: | Improved separations of a wide range of anions of environmental importance in scrubbers of waste incinerators were achieved by applying a Na2B4O7/NaOH composition gradient of low electrical conductivity in combination with suppressed ion chromatography. Fluoride, Acetate, Formiate and 16 other ions including Iodide could be separated within the same run in less than 20 minutes. The selective detection of small amounts of several anions in presence of excessive amounts of Chloride and Sulfate is discussed. Furtheron various adsorbents were tested for the removal of Phenol as a potential trouble shooting source in 5 ion chromatography. Depending on the analytical task and circumstances several adsorbents reveiled promising properties. |
