Trace-Matrix-Separation as Sample Pretreatment for the Determination of Chloride, Bromide and Iodide by Ion Chromatography in Salts, other Solid Samples and in Concentrated SolutionsChloride, bromide and iodide are collected from concentrated salt solutions on a column of Ag2CrO4. The excess of the collector is removed with acid and the silver halogenides dissolved with cyanide. The anions are separated on a PRP-X100 column using an eluent with p-hydroxybenzoic acid, p-hydroxobenzonitrile, methanol and cyanide. Detection limits are 0.2 ppm chloride, 0.04 ppm bromide and 0.2 ppm iodide, using conductivity detection and the Metrohm Ion Chromatograph 690.
