Rapid detection method of sewage oil by hyperspectral transmission

摘要

This is a rapid detection method of sewage oil by hyperspectral transmission. Obtain the transmission data of the acceptable edible oil and the oil sample to be detected in the white light hyperspectrum, and fit the equation to the wavelength X using the hyperspectral transmission value Y of the acceptable edible oil. We want to detect the equation obtained by fitting the equation to the wavelength X using the hyperspectral transmission value G of the oil sample we want to detect, using the calibration curve F (X) of the acceptable cooking oil As the hyperspectral transmission curve of the oil sample, the statistical method T-test compares the difference in each coefficient between the hyperspectral transmission curve of the oil sample to be detected and the calibration curve, and the hyperspectral transmission value of the oil sample to be detected. Analyze the degree to which the curve deviates from the calibration curve to see if the oil sample you want to detect is sewage oil The judges. The method is simple and effective, and can meet the requirement of detecting gravel oil samples quickly and efficiently by simply collecting transmission value data by hyperspectral scanning.
