“…Taking the first derivative of the mass plots highlighted the change in mass. This mass loss may be associated with the direct oxidation of organic matter and volatilization of low molecular weight hydrocarbons (Oudghiri et al 2015). The linked spectra of the Gram-Schmidt peaks ( Figure 7) were very similar for both peat samples.…”

“…The second most intense peak at 1770 cm −1 corresponds to carbonyl (C=O) stretching, which is a bond present in carbon dioxide. There was also a slight aliphatic absorption observed from 3000 to 2790 cm −1 , which corresponds to the carbon-hydrogen (C-H) stretching, possibly due to the combustion of organic carbon in the samples (Oudghiri et al 2015). The broad absorption observed at 1150 cm −1 could reflect polysaccharide absorption or the presence of water vapor (Oudghiri et al 2015).…”

“…The linked spectra of the Gram-Schmidt peaks ( Figure 7) were very similar for both peat samples. The most intense peak occurs at around 2370 cm −1 , which is indicative of carbon dioxide (Oudghiri et al 2015). The second most intense peak at 1770 cm −1 corresponds to carbonyl (C=O) stretching, which is a bond present in carbon dioxide.…”

“…Carbon dioxide has been studied as a proxy for SOM in TGA studies (Pallasser et al 2013;Oudghiri et al 2015). In the study by Pallasser et al (2013), oxygen was used as a purge gas; and as the sample was heated and volatized, carbon released from SOM was converted to carbon dioxide.…”

“…TGA is based on the continuous measurement of mass loss of a sample during heating in a controlled atmosphere (Oudghiri et al 2015). This methodology has proven to be successful when coupled with FTIR in obtaining a temporal resolution of sample components via acquisition of spectral signatures concurrent with mass loss measurements due to volatilization (Oudghiri et al 2016).…”

Characterization of soil properties typically requires time-intensive, ground-based sampling. Therefore, technologies that allow for rapid assessment of particular attributes would be greatly beneficial. One example is Fourier transform infrared (FTIR) spectroscopy, which uses an infrared spectrum to qualitatively identify a variety of compounds in solid, liquid, or gaseous samples. This study investigated the infrared reflectance signatures of peat and mineral soil samples with varying amounts of organic matter and coupled FTIR spectroscopy with a thermogravimetric analyzer (TGA) to more accurately identify and quantify soil organic matter (SOM). Clear differences were observed between the soil and peat FTIR spectral profiles. When compared to traditional analysis by loss on ignition, the coupled TGA-FTIR method resulted in an underestimation of the percent SOM for peat samples and an overestimation of the percent SOM in mineral soil samples. These results may have been influenced by low sample mass and moisture present in the sample. In total, our project results show that FTIR measurements provide a rapid yet qualitative means of assessing sample organic matter versus mineral content, but the TGA-FTIR measurement capability needs more refinement before it can be used for qualitative SOM measurements.

Covalent surface functionalization of synthesized ZnO nanoparticles (NP)s with ethylenediaminetetraacetic acid (EDTA) was successfully carried out. Modified ZnO‐EDTA NPs as a viable and inexpensive filler were incorporated into poly(vinyl chloride) PVC matrix after their chemical modification to investigate the agglomeration behavior. All prepared materials including modified NPs and PVC/ZnO‐EDTA nanocomposites (NC)s were analyzed by Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, thermogravimetric analysis, X‐ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. Fabricated PVC/ZnO‐EDTA NCs were reported to have high transparency and improved mechanical properties compared with PVC. Modified ZnO and the fabricated NCs were shown to exhibit excellent antibacterial activity against two bacteria species: Escherichia coli and Staphylococcus aureus. The obtained NCs could be considered as self‐extinguishing materials on the basis of the LOI values. Copyright © 2016 John Wiley & Sons, Ltd.
