A quantitative description of specific ion effects is an essential and focused topic in colloidal biological science. In this work, the dynamic light scattering technique was employed to study aggregation kinetics particles various alkali solutions with a wide range concentrations. It indicated that activation energies could be used quantitatively characterize effects, which supported by results effective hydrodynamic diameters, rates critical coagulation At given concentration 25 mmol...
Soil aggregate formation and stability are profoundly influenced by soil organic matter (SOM) content electrolyte conditions altering particle interactions during aggregation breakdown. However, the effect of ion-interface reaction, especially newly discovered asymmetric hybridization counterions, its coupling with SOM on accordingly breakdown remain unclear. In this study, four black soils different contents were adopted to examine kinetics using dynamic laser scattering method intensity in...
The Hamaker constant is an important material parameter for both the description of particle interaction and prediction colloidal stability. Existing methods based on classic Derjaguin–Landau–Verwey–Overbeek theory ignore Hofmeister effects would derive flawed results. In this article, approaches to estimation with without consideration were, respectively, suggested, where was obtained basis mathematic relationship between electrostatic repulsive van der Waals attractive at critical...
The different surface reactions of metal ions with variably charged soil particles can considerably influence the particle interactions, which will further aggregation, sedimentation, dispersion, and transportation. This paper presents a study aggregation kinetics colloidal at Ca 2+ Cu concentrations by using dynamic light scattering (DLS) then investigating formed aggregates structures static (SLS). From comparison experimental results, we found adsorption‐induced was much faster than...
Particle aggregation is acutely affected by Hofmeister effects. Results for behavior in the presence of effects predicted classic DLVO model were not satisfactory. In this study, description colloidal clay particles based on a theoretical relationship between ion adsorption energy and activation was established. Moreover, validity suggested theory confirmed with published experimental data montmorillonite solutions LiNO3, KNO3, CsNO3, Mg(NO3)2 Ca(NO3)2. effects, differences ability involved...
Summary Particle aggregation and aggregate breakdown are important processes that frequently occur in soil under natural conditions. However, how these two opposing affected by the forces govern particle interaction remains unclear. Thus, this research, we aimed to: (i) investigate relation between (ii) probe mechanism underlying influences of forces. Specifically, investigated a permanently charged clay‐rich solutions with different electrolyte (NaNO 3 Mg(NO ) 2 concentrations. We used fast...
Soil microorganisms are critical for soil carbon (C) cycling. They primarily regulate the turnover of organic C (SOC) by adjusting their community structure, and contributing residues with a considerable amount to resistant SOC. Nevertheless, how long-term fertilization (e.g., combination manure chemical fertilizer) affects spatial distribution both living microbial communities dead residue within aggregate fractions remains largely unclear. In this study, we analyzed changes in (lipid...
Abstract The variable role and fate of soil colloids under different environmental conditions are derived from their dispersion aggregation properties. In this work, dynamic static light scattering were used to characterize the original size, kinetics natural black (BSCs) structural features aggregates in electrolytes with cations (K + , Mg 2+ Ca ), respectively. For these three cations, followed trend > K critical coagulation concentration (CCC) sequence: (134.30 mmol L −1 ) (13.27 (4.19...
