| Abstract: | Chemometrics method was used to study near infrared spectra of ternary mixture of water,acetic acid and ethanol,which have very similar near infrared spectra because of hydroxyl group.The result shows that the mixtures could be recognized effectively by near infrared specscopy with help of chemometrics.The bilinear regression prediction model was established for estimating the composition of the mixtures, and method is simply and reliably and with good results. |
| Keywords: | Near Infrared Spectroscopy Chemometrics Water Acetic Acid and Ethanaol |
