2.3. Characterization
Fourier transform infrared (FT-IR) was performed on a
Perkin Elmer 1600 Infrared Spectrometer. FT-IR spectra of the
samples were recorded by using Nicolet’s AVATAR 360 at
32 scans with a resolution of 4 cm−1 and within the wave
number range of 4000–370 cm−1. The significant transmittance
peak at a particular wave numbers was measured by
using the “find peak tool” provided by Nicolet OMNIC 5.01
software.
