The reagent bis(salicyaldehyde)tetramethylethlemediimine (H(2)SA(2) Ten) and its copper(II), nickel(II), palladium(II), colbalt(II) and oxovanadium(IV) complexes indicate fluorescence in visible region. The conditions for the fluorimetirc determination of metals as metal chelates compounds were optimized. The linear calibrations were obtained in the range of 0-50 mu g/ml of a complex in chloroform. Solvent extraction procedure was developed for the fluorimetric determination of copper in toluene. The excitation and emission wavelengths were 370 nm and 440 nm respectively. A linear calibration curve was obtained with 0-2 mu g/ml copper in toluene. The copper in copper wires were determined and were found 79.6% (C.V. 2.5%) as compared to 82% (C.V. 0.8%) using atomic absorption.
