During the quantitative analysis of NaCl, NaOH, and β-phenylethylamine (PEA) in water samples, the highly overlapped spectra of NaCl, NaOH, and PEA resulted in poor concentration prediction. Meanwhile, the original spectral data of the natural water usually contain noise and interference spectra w...
