“…39 In the present study, HCl was chosen as a medium as it is a major component of aqua regia (3:1, HCl:HNO 3 ), which is usually used to dissolve the Zr samples. 49,50 The effect of HCl concentration on the absorption spectra of Zr–XO was carried out by varying the concentration of HCl from 0.1 to 2 M. The concentration of Zr and XO in all these solutions was maintained at 3.5 µg mL –1 and 0.005%, respectively. Figure 2a shows the variation of the absorbance of the complex at 551 nm.…”

In the estimation of Zr by UV-visible spectrophotometric technique, fluoride interference is a decade old unsolved problem. The process of repeated fuming with strong acids is often used to remove fluoride from the solution in order to estimate Zr by spectrophotometry analysis. For the first time, in this work, a simple use of AlCl3 is reported as a suppressing reagent to eliminate the interference of fluoride in the estimation of Zr. Xylenol orange in HCl medium is used as a complexing reagent. Linearity in the datum acquired from absorbance at 551 nm (λmax) is achieved over the concentration range 0.25-4.5 µg mL-1 of Zr with a molar absorptivity of 35030 L.mol-1.cm-1 and Sandell’s sensitivity of 0.003 µg.cm-2. Zr is quantified in the variety of U-Zr alloys and various water samples by using spectrophotometric detection with a classical univariate calibration with suppressing of fluoride-interference through AlCl3. Results from this novel analytical method herein developed for the first time are compared with those achieved from gravimetric analysis.
