Abstract
Bromide, iodide, and chloride are extracted from aqueous solutions into toluene-alcohol solutions of tetraheptyl-ammonium carbonate. The tetraheptylammonium halides undergo thermal degradation to 1-haloheptanes and triheptylamine. On-column preparation of the haloheptanes is achieved above 150°C. The halocarbons produce gas chromatographic peaks which are used for quantitative analysis of bromide, chloride, and iodide at low ppm levels.Keywords
