| Abstract: | A new and sensitive fluorescencequenching method for the determination of trace zirconium has been developed. It is based on the reaction of Zr() with DBAPF in the presence of the cationic furfactant CTMAB and HAcNaAc buffer solution. The maxinum exciation and emission wavelength is 521nm and 548nm respectirely. The linear range of Zr() is 0-720g/L. The detection limit of Zr() is 9.1g/L. This method has been applied to determine trace zirconium in Aluminum alloy with satisfactory results. |
