摘要：
The objective of this study was to use the EDXRF spectra to perform a multivariate calibration via partial least square (PLS) regression for Mn, Ni, Cu, Zn, Sr, Rb, Y, Zr and Nb, in soil samples and compare with univariate calibration method. The advantage of multivariate calibration is that it is not necessary to determine the net peak areas.
