CuO oxidation [1]. This method allows quantification of the released lignin-derived phenols,
however, it is time-consuming and requires previous derivatization before GC. In order to
compare the information on lignin composition provided by current routine techniques used
on soil humic acids (HA), this research compares molecular assemblages obtained from 16
HA samples by using either CuO degradation, or analytical pyrolysis (Py), as well as a nondestructive
technique such as infrared (IR) spectroscopy.Peer reviewe
