Sažetak
Solid chelating compound, phenanthrenequinonedioxime (PQDO), supported on naphthalene, provides a simple, rapid and economical means of preconcentrating copper in alloys and biological samples. Copper forms a chelate with PQDO supported on naphthalene in the column at pH 1.8—8.4. The metal complex and naphthalene are dissolved out of the column with 5 ml of dimethylformamide (DMF) and the absorbance is measured by an atomic absorption spectrometer at 324 nm. A calibration curve is linear over the concentration range 0.5—12.0 fig of copper in 5 ml of the final solution. The preconcentration factor is 80. The sensitivity for 1% absorption is 0.039 fig/ml (0.153 fig/ml for the direct AAS method from the aqueous medium). The method has been used for the determination of copper in various standard alloys and biological samples.
