Since 1947, Figure 5.6 depicts the FTIR spectrum for chitosan-NH 4NO 3 electrolytes with different salt contents in the region 1490 to 1700 cm-1. Figure 5.6: FTIR spectra of (i) pure chitosan film and chitosan with (ii) 20 wt.% NH 4NO 3, (iii) 30 wt.% NH 4NO 3, (iv) 40 wt.% NH 4NO 3 and (v) 50 wt.% NH 4NO 3 in the 1490 to 1700 cm-1 spectra region.

All infrared spectroscopies act on the principle that when infrared (IR) radiation passes through a sample, some of the radiation is absorbed. The radiation that passes through the sample is recorded. Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain infrared spectrum of absorption, emission, and photoconductivity of solid, liquid, and gas. It is used to detect different functional groups in PHB. FTIR spectrum is recorded between 4000 and 400 cm −1.

Fourier Transform Infrared (FTIR) Reference Spectra The Clean Air Act Amendments (CAAA) was published in November 1990. Title III of the Clean Air Act includes a list of 189 hazardous air pollutants (HAPS) for which test methods must be established. Fourier transform infrared spectroscopy (FTIR) is a fast, easy and reliable technique for material identification and quantification of constituents in a sample. Benefit from user-focused workflows and comprehensive FTIR performance in the lab and in the field with the Agilent FTIR spectrometer portfolio. List of Some FT-IR Spectra Examples: FT-IR of Polystyrene; FT-IR of Styrene; FT-IR of Polyacrylonitrile; FT-IR of Acrylonitrile; FT-IR of Polyethylene terephthalate; FT-IR of Silicon Compound Tetraisopropyl Orthosilicate; FT-IR of Boron Compound Boron Carbide; FT-IR of Boron Compound Boron Nitride; FT-IR of Nitrogen Compound N-methylformamide FTIR. analyticalTechniqueLongName. : Transmission Infrared (IR) Spectrum.
