“…Opvallend is dat bepaalde niet-destructieve spectroscopiemethoden, die bij biochar en bodem (Jahn et al, 2006;Linker et al, 2006;Choe et al, 2010) zijn getest, zoals PAS 1 , DRIFTS, ATR-FTIR en Raman, niet bij dierlijke mest zijn getoetst. Reviews over toepassingen van non-destructieve technieken noemen veel toepassingen voor bodem maar nauwelijks voor mest (e.g., Gredilla et al, 2016).…”

“…All spectra were recorded between 4,000 and 500 cm⁻¹ on a Bruker ALPHA FTIR Spectrometer in transmission mode. FTIR spectra interpretation was enhanced by using baseline correction and normalisation, as well as resolution enhancements including self-deconvolution (Choe et al 2010;Griffiths & De Haseth 2007;Mariey et al 2001;Naumann et al 1991). Self-deconvolution was performed on each spectrum by manually selecting the Lorentzian function and then reducing FWHH (full width of the peak at half-height) while increasing noise (Griffiths and De Haseth 2007).…”

Corrosion of ground support can lead to falls of ground, posing a significant risk to miner safety. To address this problem, the Spokane Mining Research Division of the National Institute for Occupational Safety and Health is investigating ground support corrosion at the Greens Creek mine, located near Juneau, Alaska, United States of America. Field and laboratory studies include surveys of weld-wire mesh corrosion, rock mass conductivity measurements, and sample analyses using a scanning electron microscope, energy dispersive spectrometry, and Fourier transform infrared spectrometry. Current field studies demonstrate a correlation of rock mass conductivity to the degree of weld-wire mesh corrosion and the relationship of ground conductivity surveys to support corrosion potential. Laboratory analyses of mine samples identify the presence of sulphate, which is a determinant for sulphate reducing bacteria activity. Identification of sulphate reducing bacteria (SRB) would provide evidence for microbial influenced corrosion in this mine. Ongoing research is evaluating methods of SRB inhibition. These results provide engineers with a means to map corrosion potential of the rock mass, and identify a number of paths for design of focused mitigation efforts for problem areas.

“…By comparing the nitrate peak intensity of soil pastes and their supernatant, it was shown that the nitrate dissolved in soil solution of the paste mainly responded to the FTIR signal. The results obtained are useful for the monitoring of nutrients in soils (Choe et al 2010). …”

Figure 1. Schematic representation of the electromagnetic spectrum (adapted from http://www2.chemistry.msu.edu/faculty/reusch/VirtTxtJml/Spectrpy/UV-Vis/spectrum)? Advanced Aspects of Spectroscopy 50Infrared radiation is divided into:near (NIR, ν = 10,000 -4,000 cm -1 ); -middle (MIR, ν = 4,000 -200 cm -1 ) and -far (FIR, ν = 200 -10 cm -1 ).Because all compounds show characteristic absorption/emission in the IR spectral region and based on this property they can be analyzed both quantitatively and qualitatively using FT-IR spectroscopy.Today FT-IR instruments are digitalized and are faster and more sensitive than the older ones. FT-IR spectrometers can detect over a hundred volatile organic compounds (VOC) emitted from industrial and biogenic sources. Gas concentrations in stratosphere and troposphere were determined using FT-IR spectrometers (Puckrin et al., 1996).In case of environmental studies FTIR Spectroscopy is used to analyze relevant amount of compositional and structural information concerning environmental samples (Grube et al., 2008). The analysis can be performed also to determine the nature of pollutants, but also to determine the bonding mechanism in case of pollutants removal by sorption processes. Techniques for measuring gas pollutants such as continuous air pollutants analyzer (SO2, NO2, O3, NH3), on-line gas chromatography (GC) used simple real-time instruments to quantify gas pollutants. They need to use several sensors in order to analyze multiple gas pollutants simultaneously.FT-IR spectroscopy coupled with other spectroscopic techniques such as AAS (atomic absorption spectroscopy) have been used to assess the impact of industrial and natural activities on air quality (Kumar et al., 2005;Childers et al., 2001).In addition to the traditional transmission FTIR (T-FTIR) methods (e.g. KBr-pellet or mull techniques), modern reflectance techniques are widely used today in environmental, agricultural, pharmaceuticals, and food studies. These modern techniques are attenuated total reflection FTIR (ATR-FTIR), and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The choice of the method to be used depends on many factors such as: the information needed (bulk versus surface analysis), the physical form of the sample, the time required for sample preparation (Majedová et al., 2003).In the following there will be presented some of the most important research studies related to the involvement of FTIR spectroscopy in environmental studies. Traditional transmission FT-IR (T-FTIR) spectroscopy in environmental studiesTransmission spectroscopy is the oldest and most commonly used method for identifying either organic or inorganic chemicals providing specific information on molecular structure, chemical bonding and molecular environment. It can be applied to study solids, liquids or gaseous samples being a powerful tool for qualitative and quantitative studies.
