摘要:

目的 对常见塑料类药包材红外光谱进行鉴别研究，为国家药包材标准中红外光谱鉴别提供技术支持和参考。方法 采用傅里叶转换红外（FT-IR）法采集塑料类药包材红外光谱图，对图谱中主要吸收峰进行基团归属和振动形式解析，并讨论影响红外光谱采集结果的因素。结果 对常见的塑料类药包材聚乙烯（PE）、聚丙烯（PP）、聚酯（PET）、聚氯乙烯（PVC）、聚偏二氯乙烯（PVDC）、聚酰胺（PA）红外光谱进行解析。结论 红外光谱测试方法、ATR晶体材料和生产配方等因素均会影响红外光谱采集结果。

Abstract:

OBJECTIVE To study the infrared spectra identification of common plastic pharmaceutical packaging materials and provide reference for infrared spectral identification in national pharmaceutical packaging material standards. METHOD Fourier transform infrared (FT-IR) attenuated total reflection (ATR) method was used to record the infrared spectra of plastic pharmaceutical packaging materials. The main absorption peaks in the spectra were assigned, the vibrational forms of the main absorption peaks in the spectra were analyzed, and the influencing factors of infrared spectra were discussed. RESULTS The infrared spectra of common plastic pharmaceutical packaging materials such as polyethylene (PE), polypropylene (PP), Polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), and polyamide (PA) were analyzed. CONCLUSION Infrared spectrum determination method, ATR crystal material, and production formula can all affect the results of infrared spectra.
