傅立叶红外光谱(ATR)法鉴别塑料食品包装盒

Identification of Plastic Food-packing Box with Fourier Transform Infrared Spectroscopy(ATR)

塑料食品包装盒是是人们生活中经常要用到的一种容器。塑料食品包装盒的材质有的安全无毒、耐酸耐高温,适合各种使用环境,有的存在安全隐患,比如使用温度高时会释放有毒物质等问题。该研究使用傅立叶红外光谱(ATR)法对两件塑料食品包装盒样品的材质分别进行定性鉴定。结果表明,使用傅立叶红外光谱(ATR)法分析塑料食品包装盒样品的材质,具有灵敏度高、检出速度快、所用试样量少、污染小、准确度高等优点。

Plastic food-packing box is a container often used in people's life.Some materials of plastic food-packing boxes are safe,non-toxic,acid resistant and high temperature resistant,suitable for various use environments,and some have potential safety hazards,such as the release of toxic substances when the use temperature is high.The identification method for plastic food-packing boxes by using FT-IR Spectroscopy(ATR)was studied in this paper.The result indicates that this method has some advantages such as high sensitivity,quick analyzing speed,demand for small samples,little pollution,smaller disturbance and high accuracy ect.
