“…Spectral variable selection is performed in spectroscopic techniques, because otherwise the model would be affected by unwanted variability in the spectra instead of the analyte of interest [38]. Therefore, quantitative models based on Raman and NIR uses selected spectrum ranges [30][31][32][33], hence the same is performed for UV-Vis in this study.…”

“…Then, ten PLS models were built using the calibration subset with 1 to 10 LVs. The coefficient of determination (R cv 2 ) and root mean square error (RMSECV) of the cross-validation subset were calculated for each PLS model, in a similar fashion as reported in literature for other spectroscopy techniques [30][31][32]. The R cv 2 , RMSECV and regression vector were plotted versus the number of LV used in the model as presented in Figure 11.…”

“…This technique covers wavelength range closer to the mid-infrared and broadens up to the visible region [26,27]. Typically, NIRS is primarily based on absorbance characteristics caused by vibrations of covalent bonds between H, C, O, S, and N, which are the main components of the organic matter [28].…”

“…This was achieved by quantitative evaluations of the spectral activity of sediment and soil properties [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. However, due to challenges such as the collinearity, band overlaps, and interactions for some soil properties, the spectra of soil, sediment, or suspended solids are often broad and nonspecific [25].…”
