Humic acid protein complexation [PDF]

, 2008
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.

Soil Aggregate Breakdown with Colloidal Particles Release and Transport in Soil: A Perspective from Column Experiments

Agriculture, 2022
The strongest fortresses often disintegrate from the inside. Likewise, soil internal forces play a critical role in the initial breakdown process of soil aggregate, thus accelerating soil erosion and the release of soil colloid particles.

Dilatancy, Jamming, and the Physics of Granulation [PDF]

, 2004
Granulation is a process whereby a dense colloidal suspension is converted into pasty granules (surrounded by air) by application of shear. Central to the stability of the granules is the capillary force arising from the interfacial tension between ...

Adsorption, transformation, and colloid-facilitated transport of nano-zero-valent iron in soils

Environmental Pollutants & Bioavailability, 2019
Because of its unique reductive properties, nanoscale zero-valent iron (NZVI) has been widely used in soil and groundwater remediation. It is crucial to understand the fate of NZVI in soils.

Dry-wet and freeze-thaw cycles enhance PFOA leaching from subsurface soils

Journal of Hazardous Materials Letters, 2021
Subsurface soil naturally experiences dry-wet and freeze-thaw cycles, which could affect the leaching of previously adsorbed pollutants. A slow release of poly- and perfluoroalkyl substances (PFAS) from impacted subsurface soil may serve as a long-term ...

COLLOID RELEASE AND TRANSPORT IN AGRICULTURAL SOIL AS IMPACTED BY SOLUTION CHEMISTRY

Journal of Urban and Environmental Engineering, 2011
Colloid release from the agricultural soil under unsaturated conditions was controlled by the hydrodynamic force, capillary force and electrostatic force that were determined by the solution chemistry in terms of solution ionic strength and pH.
