Environmental context The molecular organisation of humic substances is key to
understanding various natural and engineered processes, such as metal speciation and …

Humic acids are amphiphilic species whose behavior in aqueous solution suggests that they
form pseudomicelles–aggregates akin to the micelles familiar from synthetic surfactant …

For humic acid (HA) oligomers in water and soils, a novel threedimensional structural
concept is developed which is based on comprehensive investigations combining …

A critical examination of published data obtained primarily from recent nuclear magnetic
resonance spectroscopy, X-ray absorption near-edge structure spectroscopy, electrospray …

Background and hypothesis: Humic acid (HA) is of considerable environmental significance,
being a major component of soil, as well as being considered for application in other …

To gain further insight into the macromolecular behaviour of humic substances we treated a
humic material with simple organic compounds and followed the change in molecular size …

It is important to have a sound knowledge of the compositions, aspects of the structures, and
of the types of associations of humic substances (HS) because it is only through such an …

The role of lipid components in the aggregation of several humic acids isolated from different
sources was investigated using surface tensiometry. A combination of aqueous alkaline and …

Humic acid (HA) is classified as a large humic substance (HS) with a broad molecular
weight distribution of 102–106 Da which is soluble in alkaline solutions and insoluble in …

Aqueous solutions of two humic acids were subjected to UV photolysis, resulting in chain
scission of the solute. The molecular fragments were found to have diminished detergent …
