摘要
采用红外光谱法并结合二维相关光谱分析技术,对棉纤维和麻纤维进行鉴别研究。棉纤维和麻纤维在一维谱图上差别不明显,而在二维相关谱图上显示出较明显的差别。在2700~3100cm^(-1)区域内,麻纤维在同步图上的2730cm^(-1)和3020cm^(-1)附近出现两个较强的自相交峰,在2750cm^(-1)和3010cm^(-1)附近出现1个较强的和1个次强的正相交峰。在500~1000cm^(-1)区域内,棉纤维在500cm^(-1)和690cm^(-1)附近出现正相交峰,而麻纤维却在780cm^(-1)附近出现正相交峰。结果表明,二维相关红外谱图可以提高谱图的分辨率,增加谱图的识别能力,可用于棉、麻纤维的鉴别。
By using infrared spectroscopy combined with two-dimensional correlation spectroscopy,cotton fibers and linen fibers were identified.The difference of cotton fibers and linen fiber in one-dimensional spectrum was not significant,but obvious in the two-dimensional correlation spectra.In the 2500~3100cm^(-1) region,the linen fibers has two strong self-peaks at the 2730cm^(-1) and 3020cm^(-1) in the synchronous spectrum,and two strong positive peaks at 2750cm^(-1) and 3010cm^(-1).In the 500~1000cm^(-1) region,the cotton fiber has two peaks at the 500cm^(-1) and 690cm^(-1),while the linen fiber has one peak at the 780cm^(-1).The results show that two-dimensional correlation infrared spectra can improve the spectral resolution,increase the ability to identify the spectrum,and can be used for cotton fibers and linen fiber identification.
