Additional_detail: Humic acid
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.
