Interfacial and rheological properties of humic acid/hematite suspensions.
This work deals with the effect of humic acid (HA) adsorption on the interfacial properties, the stability, and the rheology of aqueous iron oxide (hematite) suspensions. It is first of all demonstrated that HA effectively adsorbs onto hematite, mainly at acid pH. Since the charge of the HA chains is negative, it will be electrostatically attracted to the hematite surface below the point of zer...
متن کاملInfluence of humic acid applications on soil physicochemical properties
7 Soil structure is often said to be the key to soil productivity since a fertile soil, with desirable 8 soil structure and adequate moisture supply, constitutes a productive soil. Soil structure 9 influences soil water movement and retention, erosion, crusting, nutrient recycling, root 10 penetration and crop yield. The objective of this work is to study, humic acid (HA) 11 application on some...
متن کاملHumic acid protein complexation
Interactions of purified Aldrich humic acid (PAHA) with lysozyme (LSZ) are investigated. In solution LSZ is moderately positively and PAHA negatively charged at the investigated pH values. The proton binding of PAHA and of LSZ is determined by potentiometric proton titrations at various KCl concentrations. It is also measured for two mixtures of PAHA–LSZ and compared with theoretically calculat...

متن کاملThe Basic Humic Acid Products
Over at least twelve years of actual field experience with an ample variety of humic acid formulations (some of them developed many years before) have given us a singular degree of expertise in Latin America and a few other markets. Among other things, we have learned to distinguish between humic acids of high biological value, and humic substances of little biological activity. We have found c...
