Applications of Ft Raman Spectroscopy for the Characterization of Cellulose
FT Raman spectroscopy was used for the investigation of cellulose and cellulose derivates. Lattice structures of cellulose, polymorphic modifications I and II, as well as amorphous structure were clearly identified by means of FT Raman vibrational spectra. Chemometric models were developed utilizing univariate calibration as well as methods of multivariate data analyses of the FT Raman spectral...
متن کاملEvaluation of Turmeric Powder Adulterated with Metanil Yellow Using FT-Raman and FT-IR Spectroscopy
Turmeric powder (Curcuma longa L.) is valued both for its medicinal properties and for its popular culinary use, such as being a component in curry powder. Due to its high demand in international trade, turmeric powder has been subject to economically driven, hazardous chemical adulteration. This study utilized Fourier Transform-Raman (FT-Raman) and Fourier Transform-Infra Red (FT-IR) spectrosc...
متن کاملLignin Quantitation by Ft-raman Spectroscopy
Because of the structural complexity of biomass, quantitation of lignin in a variety of wood and plant cell walls is difficult. Consequently, to measure lignin in different plant species, a number of different methods exist. The methods can give different values for the same material samples and such differences result from the nature of the biomass. In the past, although there have been many a...
متن کاملSensing the Structural Differences in Cellulose from Apple and Bacterial Cell Wall Materials by Raman and FT-IR Spectroscopy
Raman and Fourier Transform Infrared (FT-IR) spectroscopy was used for assessment of structural differences of celluloses of various origins. Investigated celluloses were: bacterial celluloses cultured in presence of pectin and/or xyloglucan, as well as commercial celluloses and cellulose extracted from apple parenchyma. FT-IR spectra were used to estimate of the I(β) content, whereas Raman spe...
متن کاملCharacterization of Chrysotile, Antigorite and Lizardite by Ft-raman Spectroscopy
We analyzed samples of antigorite, lizardite and fibrous chrysotile, three representative minerals of the serpentine group, to determine their chemical and structural properties, and their FT-Raman spectra. The low-frequency region of the spectrum (1200– 200 cm–1), which corresponds to the lattice-vibration modes, was then analyzed, and the observed bands attributed, on the basis of our results...
