Methylation of humic acid derived from outcrop coal by two different methods gave products with methoxyl contents which did not agree with values expected from earlier functional group analyses. The discrepancies can be explained by postulating the presence in the humic acid of activated hydroxyl gr

The humic acids, HA, extracted from a Spanish lignite and the nitrohumic acids, NHA, and nitrofulvic acids, NFA, extracted from the same lignite after its nitration, are hydrolysed with 6N HCI under reflux. Theo-amino acids present in the hydrolysates are determined and thirteen&-amino acids are ide
## Abstract The sorption properties of tetracycline were compared between a coal humic acid (CHA) and a soil humic acid (SHA) under various solution chemistry conditions. Structural characteristics of the two humic acids were quantified in detail by elemental analysis, solidβstate ^13^C nuclear mag
