摘要：
A sol-gel electrode, based on thiacalix[4]arene as a neutral carrier, was successfully developed for the detection of VO2+ in aqueous solutions. The sol-gel electrode exhibited linear response with Nernstian slope of 29.3 +/- 0.3 mV per decade, within the vanadyl ion concentration ranges 1.0 x 10(-6) - 1.0 x 10(-1) mol dm(-3). The sol-gel electrode shows detection limit of 4.9 x 10(-7) mol dm(-3). The influence of membrane composition, the pH of the test solution, and the interfering ions on the electrode performance were investigated. The electrode exhibited good selectivities for a number of alkali, alkaline earth, transition and heavy metal ions. The effect of temperature on the electrode response showed that the temperature higher than 60 degrees C deteriorates the electrode performance. Application of the electrode for the determination of vanadyl in spiked samples is reported.
