Özet
The refractive index is an important parameter to reflect the optical properties of materials, and there is a certain relationship between the component content of material and its refractive index. The Newton mixing rule can obtain the refractive indices of mixture under a certain mixed gradient. Thus, in this work we proposed a new kind of optical method for component content measurement of multivariate mixture based on the refractive index spectra, namely, the M-D-iPLS-0.01 model. We calculated the refractive indices of samples by the particle swarm double-thickness transmittance method (PTT) in the band range from 0.302 mu m to 0.9 mu m. With the mixture of distilled water and ethanol as the research objects, the prediction ability of the model was investigated, and the results show that the M-D-iPLS-0.01 model is feasible for quantitative optical analysis of multivariate mixture.
