Abstract

Six peat water samples differing in botanical composition and geographical location, along with a humic acid standard, were characterized using pyrolysis GC/FID/FTIR, pyrolysis GC/MS, and FTIR spectroscopy. Pyrolysis GC/FID/FTIR analysis revealed many by-products resulting from the thermal degradation of the major constituents of plant material: cellulose and lignin. Comparison of the pyrolysis chromatograms showed large variations in the chemical compositions of the pyrolysis products from sample to sample. Results of the FTIR analysis revealed major differences around 1000 cm-1 (C - O stretch region) and between 1500 and 1800 cm-1 (C equals C and C equals O stretch region). These two regions have previously been identified as representing cellulose and lignin, respectively. The six different peat water samples are compared based on their resulting FTIR spectra and pyrolysis chromatograms along with a comparison to the humic acid standard. Similarities and differences are emphasized along with any conclusions drawn based on these studies.
