摘要
对于常用的两种保鲜膜:PE保鲜膜、PVC保鲜膜,从外观上很难鉴别,试验利用傅立叶红外光谱(ATR)法对保鲜膜样品进行鉴别。结果表明,傅立叶红外光谱(ATR)法对于分析保鲜膜样品,分析速度快、样品需求量少,而且属于无损检测且不消耗检材,试验结果充分可靠。
For commonly used two kinds of preservative film： PE film and PVC film,it is difficult to distinguish from appearance,this test studies identification method for two kinds of preservative film by FT-IR Spectroscopy（ ATR）. The results indicate that this method（ ATR） has advantages such as high-speed,demand for small samples,undamaged,not expendable samples,and accurate and reliable experimental results.
