“…It was proposed in Bagda and Tuzen (2015) to extract the complex of reagent 2-(5-bromo-2-pyridylaso)-5-(diethylamino)-phenol with zirconium using the ionic liquid, 1-hexyl-3-methylimidazolium hexafluoro phosphate, in the presence of a surfactant Triton X-114. This technique was used for determining zirconium in water, dental materials, and artificial saliva.…”

Abstract Detailed monographs on the analytical chemistry of zirconium, which is widely used in all fields of modern science and technology, were published in the 1960s–1970s of the last century. This review summarizes information on the modern methods for determination of zirconium in a great variety of natural, technical, and biological objects. Focus is made on the works published in scientific periodicals after 2005. Spectroscopic techniques of zirconium determination including molecular and atomic spectrometry, X-ray fluorescence analysis, and electrochemical and activation methods are described. The paper also describes the applications of zirconium compounds, in particular, in analytical chemistry.

“…[36][37][38][39] For this purpose, different complexing agents such as alizarin red S, pyrocatechol violet, arsenazo III, tetrahydroxyazon SC, DMSH, hydroxyl coumarin, mordant blue, and xylenol orange have been used for the spectrophotometric detection of Zr in various samples. [35][36][37][38][39][40][41][42][43][44] For an analytical chemist, the selection of the complexing agent is always a perplexity as there are always interfering ions and no complexing agent is selective to Zr. The presence of fluoride ion is another analytical hindrance in Zr estimation by spectrophotometric technique and it is unresolved till date.…”

Method to Eliminate Fluoride Interference in the Spectrophotometric Estimation of Zirconium: Application to U–Zr Alloys

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.

“…Spectrophotometric methods occupy special position due to their simplicity, less expensive instrumentation and high sensitivity. Many methods of zirconium determination have been published [1,[3][4][5][6][14][15][16][17]. However, some of these methods have both low sensitivity and low selectivity while others have high sensitivity but low selectivity in presence of some ions or molecules.…”

A rapid, simple, selective, and sensitive method for trace determination of Zr (IV) has been developed based on the reaction of 1,4-dichloro-2,5-dihydroxyquinone in a hydrochloric acid medium to form a colored complex which is rendered water soluble by the micellar action of cetylpyridinium chloride (CPC) and measured at λmax 331 nm. Beer's law is obeyed in the concentration range 0-5 µg.ml -1 . The molar absorptivity of the complex, є was found to be 1.6 ×10 4 L.mol -1 cm -1 and Sandell's sensitivity was found to be 5.7 ng.cm -2 . A method for determination of Zr (IV) by second derivative spectrophtometry has also been proposed. The detection limit of Zr (IV) in the derivative method is 6 times lower than that of the zero order method, which shows the higher sensitivity of the derivative method. The method has been applied for determination of Zr (IV) in various samples, and satisfactory results have been obtained.
