Organic matter investigation by direct analysis of charcoal fractions using diffuse reflectance FT-IR spectroscopy
In this paper we have applied the diffuse reflectance FT-IR spectroscopy to study the organic matter structure of three fractions of charcoal (\uf8 1-2 mm, \uf8 1\u20130.5 mm and \uf8 <0.5 mm) from a burnt Pinus pinea forest. Curve fitting of different models were chosen to investigate the overlapped peaks. The best fit was reached with pure Gaussian model. This procedure gave information on nature of N-containing aromatic rings in charcoal fractions
