Özet

The determination of trace metals, e.g. Cu, Fe, Pb, Mn, Cd, Zn, Ni, in urine samples by flame atomic absorption spectrometry following their preconcentration with a cobalt-diethyldithiocarbamate coprecipitation procedure is described. The recoveries are quantitative, greater than or equal to 95%. The precision for urine analysis is in the range of 3.0-9.1% relative standard deviations at concentration level of 1.8-253.5 mu g/l.
