Chromochloris Zofingiensis

Abstract Fourier transform infrared (FTIR) spectroscopy was used in this study to identify and determine spectral features of Chromochloris zofingiensis (Dönz) Fucíková et L.A. Lewis (SAG 211-14, Gottingen, Germany), Acutodesmus obliguus (Turpin) Hegewald (SAG 276-1, Gottingen, Germany) and Chlorella sorokiniana (K. Brandt) Pröschold et Darienko (SAG 211-40c, Gottingen, Germany). Polysaccharides and lipids from these three algae species were determined using Fourier Transformed Infrared Spectroscopy (FTIR) with ATR accessory with diamante crystal in spectral range from 400 – 4000 cm−1 and resolution 4.

The composition and property of the boron mud is investigated by X-ray diffractometry (XRD), scanning electron microscope (SEM), thermogravimetry (TG), differential thermal analysis (DTA) and fourier transformed infrared spectroscopy (FITR). The mineral components of the boron mud are magnesite (MgCO3)、forsterite (Mg2SiO4)、hematite (Fe2O3)、dolomite (CaMg(CO3)2) and a small amount of magnesium sulfate and lizardite((Mg,Al)3[(Si,Fe)2O5](OH)4)). The decomposition reaction of the boron mud can be carried on at 400~600°C, and silicate of the boron mud can reaction with NaOH with the increase of temperature to about 1000°C.

Fourier Transformed Infrared Spectroscopy

Fourier Transformed Infrared Spectroscopy (FTIR) was used to study the effect of water immersion of guar gum, gelatin and pektin films. Animal-derived gelatin, citrus-derived pektin and natural guar gum made from guar seeds was used to manufacture thin films (using a 2% concentration starting solution) by casting. The biodegradable polymer films were immersed in distilled water before FTIR analysis to absorb water. The immersion time varied between 1 to 15 sec for not to make hydrocolloids, only observe swelling. After 20 sec the biofilms effectively dissolved in the distilled water.

Three main tools are used to determine the structures of organic molecules. These tools are infrared (IR) spectroscopy, mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. Infrared Spectroscopy (IR), Mass Spectrometry (MS) and Nuclear Magnetic Resonance Spectroscopy (NMR). Organic molecules absorb light (infrared, ultraviolet, etc.) at particular wavelengths based on different vibrational modes unique to the specific functional groups and structural features. In the present study, the volatile compounds of Cinnamon (Cinnamomum zeylanicum) were detected and identified by Fourier Transformed Infrared Spectroscopy (FTIR) analysis. FTIR allowed us to identify 10 volatile compounds and indicated than the functional groups of the essential oils are CHx, C=C and C=O.
