摘要
利用1 064 nm激发波长的便携式拉曼光谱仪扫描,采用随机蛙跳变量优选方法选取13个特征拉曼位移,建立偏最小二乘预测模型,分析了棉涤混纺织物中涤含量快速检测的拉曼光谱分析方法。结果表明:利用拉曼光谱法结合随机蛙跳变量优选方法可用于棉涤混纺织物中的涤含量快速检测,该方法操作简单,快速环保,具有较大的推广价值。
Scanning with Raman spectrometer with a 1 064 nm laser source, 13 key Raman shifts are obtained by Random frog variable selection method, and the least squares prediction model is established to take out a rapid determination of polyester content in cotton/ polyester textile with Raman spectroscopy method is analyzed. The results show that the Raman spectroscopy combined with random frog variable selection method can be used to rapid determine the polyester content in cotton/polyester textile, and the method features simple, rapid, environmental method and of great promotion value.
