Research on authenticity identification technique of laundry detergent based on Fourier infrared spectrum and chemical pattern recognition
This paper studied an identification technique for laundry detergents by using fourier infrared spectrum and chemical pattern recognition.This study collected infrared spectra of laundry detergent,performed first-order derivative processing on the spectra,and established a model using partial least squares discriminant analysis.The experimental results showed that the accuracy of this method is 100%,and it is simple,fast,non-destructive and high accuracy.
