1mg per litre. Only small (2 ml) samples were required, and analysis took only 6–7min. Fig. 5(a)–(d) shows some separations of metals that have been achieved using Chromopak PT and Chromopak PC columns. Lithium, sodium, potassium, ammonium, calcium and magnesium can all be determined by ion chromatographic techniques. On the Chrompack PC columns the monovalent cations (lithium, sodium, ammonium and potassium) can be separated as illustrated in Fig. 5(a). If ultraviolet absorbing acids are used in the mobile phase ultraviolet detection is possible.

5 (b)). The cations of the transition metals which do not have sufficient retention on the Chrompack PC column can be separated on the Chrompack PT column (Fig. 5 (c)). 2 Ammonium ion Mizobuchi et al. 0) and acetonitrite (65:35 v/v). The analytical recovery was examined by spiking river water, effluent and rainwater with known amounts of ammonium. 4. Reproducibility was measured with standard solution, river water, effluent and rainwater. 28%. The detection limit was 6 µg L−1. Typical chromatograms obtained for a rain water and a river water are shown in Fig.

Pyrohydrolysis apparatus, combustion conditions and adsorption of the inorganic anions were optimised for the complete conversion of several model compounds such as 4-chlorophenol, 4-bromophenol, 4-bromobenzoic acid, thiobenziamide and toluene sulphonic acid and maximal anion recoveries. 1 Carboxylic acids Various workers have used ion chromatography to determine low molecular weight carboxylic acids in wastewater [3] and rainwater [4,5]. Detection limits in the three methods were less than 1µg mL−1.
