| Abstract: | The optimal model for chemical oxygen demand(COD) in wastewater was founded by near-infrared spectroscopy analysis combined with moving window partial least squares(MWPLS) method.According to the prediction effect,the optimal model was selected,and the corresponding waveband,number of adopted wavelengths,PLS factor,RMSEP,RP were 820-850nm,16,13,25.5 mg/L,and 0.968 respectively,which was obviously superior to the optimal PLS model on the whole spectral collecting region.The result indicated that the MWPLS me... |
