“…In Arida (2008) and Gupta, Goyal, and Sharma (2009), the authors describe some examples of the application of electrodes selective to organic reagents for the indirect determination of zirconium, which forms a complex with them. So, a sensor with a membrane containing thoron (4-((2-arsonophenyl)azo)-3-hydroxy-2,7naphthalenedisulfonic acid) was used for determining 1.8•10 −4 -2.6•10 −3 mol•l −1 of zirconium (Arida 2008). A sensor with membrane based on alizarin red S was used for determining 5-28 μg•l −1 zirconium in solutions of alloys (Gupta, Goyal & Sharma, 2009).…”

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.

“…For the fabrication of the organic membrane-based microsensor part, a cocktail-coating mixture incorporating the copper(II) ionophore has been utilized. The stock solution of this cocktail-coating mixture was prepared as described elsewhere [24] by mixing thoroughly 33 mg of powdered PVC, 57 mg of o-nitrophenyl octyl ether plasticizer, 3 mg of potassium tetrakis (p-chlorophenyl) borate anion excluder and 7 mg of o-xylylene bis(N,N-diisobutyldithiocarbamate) copper(II) ionophore in a small beaker. The mixture was then completely dissolved in 5 mL THF.…”

A first step towards the microfabrication of a thin-film array based on an organic/inorganic sensor hybrid has been realized. The inorganic microsensor part incorporates a sensor membrane based on a chalcogenide glass material (CuAg-As-Se) prepared by pulsed laser deposition technique (PLD) combined with an PVC organic membrane-based organic microsensor part that includes an o-xylyene bis(N,N-diisobutyl-dithiocarbamate) ionophore. Both types of materials have been electrochemically evaluated as sensing materials for copper(II) ions. The integrated hybrid sensor array based on these sensing materials provides a linear Nernstian response covering the range 1 Â 10À1 of copper(II) ion concentration with a fast, reliable and reproducible response. The merit offered by the new type of thin-film hybrid array includes the high selectivity feature of the organic membrane-based thin-film microsensor part in addition to the high stability of the inorganic thin-film microsensor part. Moreover, the thin-film sensor hybrid has been successfully applied in flow-injection analysis (FIA) for the determination of copper(II) ions using a miniaturized home-made flow-through cell. Realization of the organic/inorganic thin-film sensor hybrid array facilitates the development of a promising sophisticated electronic tongue for recognition and classification of various liquid media.

A simple preconcentration method for zirconium based on coprecipitation with aluminium hydroxide prior to flame atomic absorption (FAAS) determination was established. The recovery values of the analyte ions were higher than 95%. Such parameters as the type of hydroxide ion source for precipitation, type of acid for the dissolution step, amount of Al 3+ ion as the collector, pH, temperature, standing time and centrifuge time were optimized using 50 mL of a solution containing 150 g of zirconium. The effect of the solution volume and influences of matrix ions on the extraction of the analyte were also examined. Under the optimum conditions, the calibration curve was linear up to 10 mg L −1. The relative standard deviation for solutions containing 150 g of zirconium was found to be 3.9%. The limit of detection (LOD) and limit of quantitation (LOQ) were calculated as 0.17 and 0.57 mg L −1 , respectively. The method is capable of extracting the analyte in different samples with volumes of up to 250 mL. The preconcentration factor for 250 mL and enhancement factor for 50 mL of analyte solution were calculated to be 250 and 40, respectively. The proposed method was successfully applied for the determination of zirconium in glass and refractory brick samples.
