Fecha de publicación: | 1992 | Editor: | Elsevier | Citación: | Science of the Total Environment 117/118: 335-343 (1992) | Resumen: | Three Spanish lignites of similar low maturity level taken from different deposits and their humic acid (HA) fractions have been characterized by chemical and spectroscopic methods. Some remarkable differences were found in the HA contents, as well as in the distribution of humic and fulvic fractions among the parent lignites. These differences, however, are not reflected by spectral or chemical distinguishing features. The results suggest that ligninderived materials contributed to the formation of the lignite deposits. | Descripción: | a) Instituto de Recursos Naturales y Agrobiología, C.S.I.C., P.O.
