B Gong,G Gong,

A new fluorometric method has been developed for the determination of trace zirconium, based on the fluorescence quenching effect of Zr (IV)-5'-nitro-salicylfluorone (5'-N-SAF)-hexadecyltrimethylammonium bromide (CTMAB). In the H2SO4 medium and in the presence of CTMAB Zr (IV) reacts on 5'-N-SAF to form a 14 orange complex. Its maximum excitation wavelengths are 475 and 505 nm,and the maximum emission wavelength is 525 nm. The linear range is 2.0-80 microg/L, and the detection limit is 2.0 microg/L. The method has been applied to the direct determination of trace Zr (IV) in the aluminium alloy reference sample with satisfactory results.
