Simultaneous kinetic determination of Fe(II) and Fe(III) based on their reactions with NQT4S in micellar media by using PLS and PCR methods

Simultaneous spectrophotometric determination of trace amount of malachite green and crystal violet in water after cloud point extraction using partial least squares regression

“…Interested readers can refer to references [22][23][24][25][26][27][28][29][30] for its further information. As two full spectrum multivariate calibration methods, PLS and principal component regression (PCR) only need to know the concentration of the analyte of interest in the calibration samples and it is unnecessary to know the concentration of other analytes.…”
