| Abstract: | The ATR technique was applied to collect IR spectra of the samples and partial least square was used to determine the plasticizer content of di(2-ethylhexyl) adipate (DEHA) in PVC thin films for wrapping foods. The results show that the linearity of the standard sample curves is excellent, with a correlation coefficient of 0.9999. This method is simple, reliable, rapid, free of the influence of the substrates and suitable for quality control of line production. |
