Abstract

An apparatus and technique for the simultaneous determination of cadmium by atomic fluorescence and lead by atomic absorption Spectrometry are described. A common dithizone-chloroform extraction procedure is used for the analysis of plant material and soil extracts with the carbon-rod atomizer. Detection limits in solution of 0.002 ppm for cadmium and 0.035 ppm for lead are obtained with a precision of ±2–6% and minimal interference effects.
