Ir spectrum of chitosan
WebApr 7, 2024 · The IR spectra of ACGG-2 and ACGG-3 point out the existence of new bonds between AV, CS, and glutaraldehyde as the spectra exhibit characteristic peaks at a particular area. A wide peak at about 3400 cm −1 is noticed, which is the stretching vibration mark for the O-H group. WebFourier transform infrared spectroscopy (FT-IR) analysis was applied to confirm the chemical structure of the modified materials.
