几种塑料的拉曼光谱检测

摘要

The Raman spectroscopy technology was employed for the determination of several kinds of plastic. The standard Raman spectra of polyethylene terephthalate ( PET), polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS) and polycarbonate (PC) were obtained. By comparing the Raman spectrum of the sample and the standard Raman spectum, the plastic sample could be identified rapidly and accurately. Using this technology, the sample will not be damaged and could be tested directly.%应用拉曼光谱技术,对食品包装用几大类塑料材料进行了检测和分析.获得了聚对苯二甲酸乙二醇酯、聚乙烯、聚氯乙烯、聚丙烯、聚苯乙烯、聚碳酸酯的标准拉曼光谱.通过将实际检测样品和数据库中标准拉曼光谱的对比,可以快速准确地鉴定出检测样品的种类.同时该技术具有对检测样品无损和直接检测的优点.
