傅立叶变换红外分光光度法测定棕榈氯霉素A晶型的含量

Determination of the Chloramphenicol Palmitate Polymorph A Using FTIR Spectroscopy

摘要: 目的：建立红外分光光度法测定棕榈氯霉素A晶型的方法。方法：采用分辨率为2cm^-1的傅立叶变换红外分光光度计进行测定。结果：棕榈氯霉素A晶型在843cm^-1处的吸收强度与含量成线性关系，用透光率表示时，线性方程为y=95.68-0.9425x，相关系数r=-0.9983。用吸度表示时，线性方程为y=0.01169 0.005424x，相关系数r=0.9943.:一法具有快速，简便，准确，重现性好的特点。
