SPECTROPHOTOMETRIC DETERMINATION OF VANADIUM(IV) ION USING XYLENOL ORANGE REAGENT
Abstract
The determination of vanadium(IV) ions in environmental and industrial samples is an important analytical task due to their biological and ecological significance. In this study, a spectrophotometric method for the determination of vanadium(IV) ions is proposed. Xylenol Orange was selected as a sensitive analytical reagent, and the reflectance spectra of the vanadium(IV)–Xylenol Orange system were recorded using an EMC-30PC-UV-1800 UV–Vis spectrophotometer. The optimal conditions for complex formation, including pH and reaction time, were investigated. The developed method demonstrated good sensitivity, selectivity, and reproducibility, making it suitable for the determination of vanadium(IV) ions in real samples.
