摘要：
Optimum leaching conditions for the fly ash are predicted as L/S ratio: 20 mL/g, temperature: 78 °C, time: 240 min, and NaOH concentration: 4 M.The maximum recovery of vanadium reaches 66.7% under the optimum leaching conditions.The recovered nanostructured V2O5 has a 37.5% smaller average crystallite size than the pure nanostructured V2O5.The recovered nanostructured V2O5 exhibits up to 60% higher sensitivity toward ethanol compared to the pure nanostructured V2O5.
