Simultaneous Determination of Potassium and Sodium in Cigarette Paper by Near Infrared Spectroscopy

In order to meet the needs of rapid analysis of potassium and sodium in cigarette paper,the near infrared(NIR) spectra of 101 representative cigarette paper samples by measured by FT-NIR spectroscopy,and the contents of K and Na were determined by the chemical method.Based on the spectral data and determined chemical results,PLS calibration models were developed and optimized for the rapid quantitative analysis of K and Na,Results showed that it was suitable to use 14 papers to scan the samples.The optimize...
