Ftir spectrum of fe3o4
WebJul 26, 2016 · To better characterize the phase and composition of the prepared nanoparticles, FTIR analysis was performed. Figure 3 exhibits the IR spectra of the prepared nanoparticles. The FTIR spectrum of the uncoated NPs (in Figure 3(a)) has the characteristic absorbance bands of nanosized magnetite, that is, two strong bands … WebFTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.
