摘要
建立了拉曼光谱法测定维生素C片。以0.1 mol/L乙酸提取样品,用智能激光拉曼光谱仪分析,以维生素C的拉曼特征位移峰进行定性,以拉曼指标峰面积进行定量。维生素C在20~250 mg/ml范围内线性关系良好,平均回收率为99.53%,RSD为1.12%。
A Raman spectroscopy method was established for the determination of vitamin C tablets. The samples were extracted by 0.1 mol/L acetic acid, and was analyzed by smart laser Raman spectrometer. It was qualitatived by Raman characteristic peak shifts, and quantitatived by Raman index peak area. It was linear in the range of 20 - 250 mg/ml. The average recovery was 99.53 %, with RSD of 1.12 %.
