Anwendung von ionenaustauschverfahren zur bestimmung von spurenelementen in natürlichen wässern—V: Blei

A method is described which makes possible the separation of lead from natural waters at the ppM level, and its final determination by spectrophotometry or atomic absorption. The sample is made 0.15M in hydrobromic acid, filtered, and passed through Dowex 1 X8 (bromide form). The lead is sorbed on the resin and most of the other elements present are separated from it. The lead is eluted with 6M hydrochloric acid and determined by the dithizone method or by atomic-absorption. The method was used to determine lead in drinking water and water from the Danube, lead concentrations in the range 2–14 ppM being found.
