Abstract
The coupling of aromatic diazonium salts with humic or nitrohumic acid, as a supplemental method of determining the structure and utilization of humic acid, were studied. The following results were obtained. 1) Humic acids have many vacan to-and p-positions in their phenol kernels. 2) Humic acids have not so many benzene kernels in their structure units. 3) When coupled with aromatic diazonium salts (such as aniline, aminonaphthalene and aminoanthraquinone derivatives), various azo-dye were obtained.
