Additional_detail: Humic acid is one of the major
components of humic substances.
Chemically, it is a super-molecular
aromatic acid composed by various
functional groups, taking on
effects of sorption, complexation,
chelation, flocculation, which
dissolves loads of hydrophobic
matters. They can also be found in
peat, coal, many upland streams and
ocean water.
Major applications
Humic acid is mainly employed in
industry in forms of additive, its
effects are: to improve product
quality, to retrench raw material
and to reduce energy expenditure;
for instance, it may be applied as
boiler water soften agent and as
petroleum drilling fluid decreasing
and filtering agent. By chelating
the ions, humic acids facilitate
the uptake of these ions by several
mechanisms, one of which is
preventing their precipitation,
another seems to be a direct and
positive influence on their
bioavailability. They also dissolve
loads of hydrophobic matters and
along with the above characteristic
they take care of harmful matters,
preventing waters from contamination.
Since their pH values are below 7,
namely acidic, humic acids
alleviate the world-challenging
issue of soil salinisation.
