Abstract：A reagent of N’1,N’2-bis[(1E)-(2-hydroxyphenyl)methylene]ethanedihydrazide (DSOD) was synthesized, and characterized by IR spectra and element analysis. A highly sensitive fluorimetric method for the determination of trace amounts of zinc was proposed based on the reaction of Zn2+ with DSOD in ethanol at pH 7.00. The linear range of the method was 0-65.0 μg·L-1 with a detection limit of 0.30 μg·L-1. The interferences of 16 common ions were investigated and the results showed that the DSOD had a good selectivity. The analytical results of detecting trace amounts of Zn2+ in zinc rich salt and hair by this method were satisfactory.
