A new fluorimetric reagent, salicylaldehyde benzalhydrazone has been established.The fluorimetric reaction of the reagent with copper was carried out in aqueous medium at pH=9.0 and studied in detail. The fluorescence excitation and emission wave-lengthsof the complex are 300 nm and 410 nm respectively. The linear range is 0.0～0.8 μm/10mL,the detection limit is 12. 4 ng/mL and the molar ratio of copper to the reagent is 1:1.The method has been applied to the determination of trace copper in tea and hair with satisfactory results.
