Abstract

The present review focuses on the spectrophotometric determination of tungsten(VI) using a wide range of organic reagents and their derivatives. Organic ligands have gained considerable importance in analytical chemistry due to their strong ability to form stable and highly colored complexes with tungsten(VI), which enhances the sensitivity and selectivity of spectrophotometric analysis. Various chromogenic reagents reported in the literature for tungsten(VI) determination have been critically examined and compared on the basis of their analytical performance and applicability. The review discusses important experimental variables affecting complex formation, including pH, acidity, solvent medium, reagent concentration, extraction conditions, and reaction time. Significant analytical parameters such as Beer’s law range, molar absorptivity, Sandell’s sensitivity, detection limits, precision, accuracy, and tolerance toward interfering ions have also been evaluated systematically. In addition, the coordination behavior of tungsten(VI) with different organic ligands, along with factors influencing the stability and absorbance characteristics of the resulting complexes, has been discussed in detail.

Keywords: Tungsten(VI), spectrophotometry, trace analysis, UV–visible spectroscopy, analytical chemistry, selectivity, detection limit, molar absorptivity, Sandell’s sensitivity
