Abstract

Surface morphologies of softwood and hardwood lignin-carbohydrate complexes, and of humic and fulvic acids (the products of biochemical degradation of plant matter in soil) were examined under identical conditions using atomic force microscopy coupled with transformation of digital images into Virtual reality. The structural organization of the observed surfaces did not always coincide with that found previously using electron microscopy, suggesting that sample preparation played a significant role in the formation of aggregates. Morphological differences were observed in the samples that belonged to the same class of materials and to different classes. The morphologies of lignin-carbohydrate complexes and humic and fulvic acids followed a similar pattern, however, suggesting similarities in the chemical structure of both classes of compounds.
