Cation binding by humic substances

Humic substances are highly abundant organic compounds formed in soils and sediments by the decay of dead plants, microbes and animals. This book focuses on the important binding properties of these compounds that regulate the chemical reactivity and bioavailability of hydrogen andmetal ions in the natural environment. Topics covered include the physico-chemical properties of humic matter and i...

HUMIC SUBSTANCES Capillary Zone Electrophoresis

Humic substances (HS) which are widespread in the soil, present structural complexity and polyelectrolyte properties. Many techniques and methods have been used to obtain more information about them, as reviewed by Davies and Ghabbour in 1999. The characterization of HS has been the focus of intense research for many years because the organic matter in soil contributes to the quality of the soi...

Health Value of Humic Substances

It has been found that humic acid in dose levels of 100-300 milligrams per kilogram body weight has no effect on bleeding time, clotting time, thrombin time, plate count, or induced platelet aggregation (49). Red blood cells and hemoglobin stay on normal levels under the influence of humate in comparison with control groups (15). Literature has indicated that the red blood cells have the capabi...
