本文采用单波长激发能量色散X射线荧光光谱法(Monochromatic wavelength dispersive X-ray fluorescence spectroscopy,MWD XRF)测定煤炭发热量,解决常规X射线荧光光谱对金属氧化物检出限不足的现状,同时采用多元线性回归分析建立发热量计算模型,解决煤炭的基体干扰与定量问题,并结合X射线荧光光谱对样品无损、样品处理简单等特点,完成煤炭发热量的快速定量检测.本研究满足了煤炭发热量快速检测的需求,为煤炭生产、流通、通关等各个环节提供发热量快速检测方法.
Study on Rapid Determination of Dry Basis Perch Calorific Value of Coal Based on Monochromatic Wavelength Dispersive X-ray Fluorescence Spectroscopy
In this paper,monochromatic wavelength dispersive X-ray fluorescence spectroscopy(MWD XRF)was used to determine the calorific value of coal,coping with the insufficient detection limit of metal oxides by conventional X-ray fluorescence spectroscopy.Multiple linear regression analysis was used to establish a calorific calculation model to solve the problem of matrix interference and quantification of coal.Combined with the characteristics of X-ray fluorescence spectroscopy of being non-destructive and easy-to-operate,the rapid quantitative detection of calorific capacity of coal was completed.This study satisfies the needs of rapid detection of calorific value of coal,and provides a rapid calorific detection method for all links and processes from coal production,circulation to customs clearance.
