A two-step thermochemolysis for Soil Organic Matter analysis. Application to lipid-free organic fraction and humic substances from an ombrotrophic peatland.
Original language description
A two-step off-line thermochemolysis was developed to characterize successively free and bound compounds in humic fractions. Two reactants with different strengths were used: hexamethyldisilazane (HMDS) followed by tetramethylammonium hydroxide (TMAH). Analysis of the thermolysates showed obvious differences between the two steps regarding the nature and/or the distribution of the numerous identified products. The first step with HMDS revealed the occurrence of thermolabile compounds and/or molecular units occurring initially in (bio)polymers susceptible to be cracked by HMDS, mostly carbohydrates and aromatics. The second step with TMAH released products resulting from the cracking of units with a relatively high thermal and/or chemical stability (monomers from biopolymers such as lignin and cutins, suberins or waxes). Two-step thermochemolysis thus appears as an interesting tool to help deciphering the composition, origin and nature of soil and sediment organic matter. Moreover, the
