Preparation and Application of Yttrium Nanoparticles as a Fluorescence Probe for Determination of Hesperidin
摘要
Abstract
Yttrium nanoparticles (Y-NPs) had been prepared by chemical reduction method with yttrium ion as the raw material. The effect of ionic liquids on the synthesis of (Y-NPs) was investigated. The image of transmission electron microscopy (TEM) showed the particles were yttrium nano-particles. The fluorescence spectral of Y-NPs was studied. Based on the fluorescence enhancement of Y-NPs in the presence of hesperidin, a novel method for the determination of hesperidin was proposed. The result showed that the fluorescence enhancement value of the Y-NPs was linearly proportional to the concentration of hesperidin in the range of 0. 18 -14. 40 mg/L with a correlation coefficient of 0. 9991. The limit of detection was found to be 0. 05 mg/L. The simple method has been applied to the quantification of hesperidin in actual samples with satisfactory results.关键词
