Preliminary investigations have shown, that considerable losses of lead occur during storage of the organic APDC/MIBK-extracts. Therefore, it was necessary to reextract lead into the aqueous phase by nitric acid. Investigations of recoveries confirmed, that extraction and reextraction of lead were quantitative. In this way the concentration of lead is increased by a factor of five. Mean standard deviations for four concentration ranges are given. A detection limit of 0.16 mg of Pb/l is obtained, which is lowered by the preceding enrichment to about 0.03 mg of Pb/l. Details of the procedure are given.
