摘要
研究了傅里叶变换红外光谱 (FTIR)直接测定丙二醇水溶液中丙二醇含量的方法。结果表明 ,样品无须做前处理 ,丙二醇的含量与其红外吸收峰强度在实验浓度范围内皆有良好的线性关系 ,回收率为10 0 .0 %— 10 1.4 %,相对标准偏差为 0 .146 %,该方法简单、快速 ,测定结果令人满意。
The content of propanediol in aqueous solution has been directly studied by FTIR. Results show that the linear relationship between the height of peak and the content of propanediol is excellent without the pre-treatment for samples.This method is simple and rapid with satisfactory results. The recovery rate are in the range of 100.0%-101.4% and the RSD is 0.146%.
