| Abstract: | The FTIR spectrometry was used to determining the total degree of substitution( DS 1) of phthaloyl chitosans(PHCS) and degree of substitution of phthaloyl imide groups(DS 2). The probe bands, reference bands and baselines in IR spectra were investigated for the determination. The DS s were also determined by 1H NMR and elemental analysis for comparison. Based on the average relative deviations of ( A probe band / A ref band ) to DS in FTIR spectra the most suitable A PB / A RB ) was found to be A 1 712BL1 / A 1 391BL3 for DS 1 calculation, and A 1 775BL1 / A 1 654BL1 for DS 2, where BL 1, BL 2 and BL 3 are the baselines in IR spectra(Fig.1). |
