| 摘 要： | 利用丙三醇(CH2OHCHOHCH2OH)在1115.9-994cm-1处有C-O伸缩振动的红外特征吸收峰,而水在此无吸收峰,采用衰减全反射红外光谱法,并用OPUS软件进行ATR较正来测定水溶液中丙三醇的含量.测定结果表明,丙三醇的含量与其红外吸收峰高、峰面积在实验浓度范围内皆有良好的线性关系,峰高和峰面积的校准曲线相关系数分别为0.997和0.998,操作步骤简单、快速,测定结果令人满意. |

| Abstract: | The content of glycerin in aqueous solution was directly determined by ATR-FTIR based on the characteristic peak of 1115. 9-994cm^-1 in infrared spectra. The linear relationships between the peak height or peak area and the content of glycerin are excellent without the pretreatment for samples with correlation coefficients of 0. 997 and 0. 998,respectively. This method is simple and rapid with satisfactory results. |
