A new method has been proposed for the atomic absorption spectrophotometric determination of zinc, cadmium and lead after coprecipitation of their morpholine-4-carbodithioate complexes with microcrystalline naphthalene. They are easily coprecipitated over the pH range, Zn:3.7-9.4, Cd:3.3-11.0 and Pb:5.4-10.2. The compound coprecipitated with solid naphthalene is separated by filtration, dissolved in 2 M nitric acid and made up to 25 ml with nitric acid. The metals are determined by measuring absorbance at 213.9, 228.8 and 217.0 nm for zinc, cadmium and lead respectively. Beer's law is obeyed up to Zn:23μg, Cd:45 μg and Pb:200μg per 25 ml of the final solution. Ten replicate determinations of a sample solution containing, Zn:10μg, Cd:20μg or Pb:50 jag gave mean absorbances of 0.105, 0.095 and 0.053 with relative standard deviations of 1.42, 1.57 and 2.20% respectively. The developed method has been applied to the determination of these metals in some standard samples.
