| Abstract: | Based on the singular value decomposition (SVD) of absorbance matrix and the pseudoinverse A +,a modified matrix algoritim was developed,in which the optimal calibration matrix is determined by the PRESS of the calibration set.The algorithm combined with chromazurol S CTMAB actone high sensitive color system is used to simultaneously determine the trace amount of Fe,Al,Sc in their mixtures,the relative error of Fe,Al,Sc are 3.5%,9% and 13% respectively. |
