Multiple Sallen-Key smoothing filter method of XRF energy spectrum and its application in rice cadmium content analysis

BackgroundIn the measurement of trace nuclides, the characteristic peaks are easily partly or completely obstructed by the background.PurposeThis study aims to apply multiple Sallen-Key (MSK) filter to the trace nuclides in X-ray fluorescence (XRF) energy spectrum, and verify its application in rice...
