NIR spectra of plastic wastes with different color,thickness,and particle size of polymermaterials were measured by using a portable MR spectrometer to investigate their effects for the(iiscrimination of plastic materials. MR and UV/vis spectra for80pieces of wastes plastic were measured and analyzed by princi.pal component analysis(PCA)after standardization.The MR spectra for different color samplesha〔l a little〔iifference in the shape and the intensity, These differences coul(i be brought by thedifference of pigment additives and its particle size in each sample.And the results for PCAindicated that the co1Qr and form of the plastic samples were not affected to the discrimination ofthe plastics.It was also found that the types of waste plastic were discriminated by PCA withbarcode NIR spectra effectively.
