The copper chelate of APDC was adsorbed on microcrystalline naphthalene to determine trace amounts of copper. The optimum pH range for the adsorption is 1.5–10.5. The chelate in dimethylformamide has an absorption maximum at 435 nm. Beer's law holds in the range 2.5–48 μg of copper in 10 ml of dimethylformamide. The molar absorptivity is 1.3×10<SUP>4</SUP>l·mol<SUP>−1</SUP>·cm−1 and the sandell sensitivity 4.8×10<SUP>−3</SUP>μg of copper per cm<SUP>2</SUP>. Other factors such as amounts of reagent and naphthalene, shaking time, standing time and diverse ions were studied. The method can be applied to the determination of copper in Bovine Liver and human hair.
