摘要
This paper describes the simultaneous spectrophotometric determination of copper, zinc, nickel and cobalt in water with 5-Br-PADAP. The absorbance spectra obtained were processed with wavelet transform (WT) for removal of noise from the spectra. In order to eliminate spectral interferences, calculation of the metal concentrations in mixtures was performed using principal component regression (PCR). The results showed that the combination of MT and PCR allowed more accurate and precious spectrophotometric determination of these ions than traditional PCR approach.
