Application of the X-ray Fluorescence Spectrometer in Detecting Lead and Cadmium Content in Farmland Soil
The previous methods for detecting lead and cadmium in farmland soil are not always satisfactory due to their limitation to a single feature through the spectral data.Therefore,this paper aims to study how the X-ray fluorescence spectrometer is applied to the detection of lead and cadmium contents in farmland soil.First,we adopted an X-ray fluorescence spectrometer to obtain the corresponding soil sample spectral data,and performed wavelet and correction processing on the spectral data.Then,we extracted multiple spectral data and projected them.Finally,we calculated the corresponding weight values to complete the analysis of the spectral data characteristic components.As a result,we could obtained the contents of lead and cadmium elements through calculating their absorbance.On this basis,we complete the design of a method for detecting the contents of lead and cadmium elements in farmland soil.In experimental testing,In conclusion,the designed method has a rather higher degree of fitting and better detection effect in practical applications.
