A spectrofluorimetric method is described for the determination of 2 to 16 μg of zirconium based on the formation of an ion-association complex with salicylic acid and Rhodamine B. Hafnium behaved similarly to zirconium, but the interference can be overcome by selective extraction of zirconium at pH 1.4–1.6 from 1 mol dm<SUP>−3</SUP> chloroacetic acid medium into 0.3 mol dm<SUP>−3</SUP> solution of salicylic acid in 2:3 mixture of isobutyl methyl ketone (IBMK) and chloroform. The spectrofluorimetric method in conjunction with the separation procedure has been used for the determination of 4.4 to 14.5% of zirconium in hafnium metal.
