What are the effects of bentonite on the winemaking process?4 answersBentonite has various effects on the winemaking process. It can be used as a fining agent to remove unstable proteins and prevent protein haze formation. The dosage and timing of bentonite addition are important factors that can affect the volatile profile, foam characteristics, and sensory properties of the wine. Bentonite can also influence the phenolic composition, color characteristics, and antioxidant activity of the wine, with higher doses having a stronger impact. When added during fermentation, bentonite can reduce the total dose required for protein stability and preserve more phenolic compounds and volatile aromas, leading to positive sensory effects. Additionally, bentonite has been found to be an efficient fining agent for the removal of aflatoxins from white and red wines, although it may have a slight impact on the color of red wine.
How to account for the volume of the adsorbed phase and the interlayer diffusion process in compacted bentonite?4 answersTo account for the volume of the adsorbed phase and the interlayer diffusion process in compacted bentonite, a modified diffusion/adsorption model has been proposed. This model considers the volume of the adsorbed phase and suggests that diffusion through highly compacted clay occurs in the interlayers, or the adsorbed phase. The model emphasizes the need for more detailed descriptions of surface reactivity and the mobility of interlayer species to quantitatively predict the diffusive flux. Additionally, the integrated sorption and diffusion (ISD) model has been developed to quantify radionuclide transport in compacted bentonite. The ISD model incorporates the excluded volume effect and the dielectric saturation effect, and solves the modified Poisson-Boltzmann equations to improve the applicability of the model for multivalent ions and complex species. The ISD model has been successfully tested for various actinides with complex chemistry, showing quantitative agreements with diffusion and sorption data.
Modeling approaches for cation in compacted bentonite?5 answersModeling approaches for cation behavior in compacted bentonite have been explored in several studies. Birgersson proposed an approach that treats chemical equilibrium between bentonite and aqueous solutions by conceptualizing bentonite as a homogeneous mixture of water and montmorillonite. This approach considers Gibbs-Donnan membrane equilibrium and derives an equation for calculating the electrostatic potential difference between bentonite and external solution (Donnan potential). Yotsuji et al. developed the integrated sorption and diffusion (ISD) model, which quantifies radionuclide transport in compacted bentonite. The current ISD model, based on the Gouy-Chapman electric double layer theory, can account for diffusion of monovalent cations and anions. To improve the model's applicability for multivalent ions and complex species, modifications were made to consider the excluded volume effect and the dielectric saturation effect. Tournassat and Appelo developed a predictive model that considers clay microstructure changes as a function of bentonite compaction and ionic strength. This model relates the interlayer porosity to the ionic strength and the montmorillonite bulk dry density, providing a good fit for measured anion accessible porosities in bentonites.
What is the interrelationship of effective and apparent diffusion coefficient for sorbing radionuclide in compacted bentonite?5 answersThe interrelationship between the effective and apparent diffusion coefficients for sorbing radionuclides in compacted bentonite is influenced by factors such as the compacted dry density, the presence of barite precipitates, and the microstructure of the bentonite. The effective diffusion coefficient decreases with increasing compacted dry density and with the formation of barite precipitates. The accessible porosity and the interlayer porosity also play a role in the diffusion behavior, with changes in these porosities affecting the effective diffusion coefficient. Additionally, the diffusion profile of radionuclides in compacted bentonite can be exponential, indicating limited pore size availability for diffusion. The diffusion coefficients of sorbing radionuclides onto compacted bentonite can be measured using various techniques, such as the flow-through method and the profile method. Overall, the diffusion parameters for sorbing radionuclides in compacted bentonite are influenced by factors such as dry density, porosity, and the presence of precipitates, which affect the interrelationship between the effective and apparent diffusion coefficients.
How bentonite colloid generated are what are their properties ?5 answersBentonite colloid generation and their properties were investigated in several studies. The size distribution of the generated colloids was analyzed, and it was found that the maximum concentration of bentonite colloid in solution corresponds to particles with a size around 50-100 nm. The concentration of particles of smaller size (50-100 nm) was always higher in the absence of calcium, indicating the clear effect of this element on their aggregation. Colloid generation was observed for ionic strengths lower than the critical coagulation concentration, and the pH and ionic strength were found to be important factors in colloid stability. Bentonite colloids were found to have a high sorption capacity for uranium(VI) and their sorption was dependent on pH, ionic strength, and carbonate concentration. The retention and release of bentonite colloids in porous media were influenced by dispersion stability, filtration effect, and solution chemistry. These findings provide insights into the formation, stability, and behavior of bentonite colloids, which are important for understanding their potential role in radionuclide migration and contaminant transport in geological repositories.
What is COMSOL advantages and disadvantages in calculate effective diffusion coefficient?5 answersCOMSOL has advantages and disadvantages in calculating the effective diffusion coefficient. One advantage is that it can replicate Turing patterns in reaction systems with subdiffusion using an effective system with Markovian cross-diffusion. This allows for the capture of transient dynamics and the efficient description of the Turing instability. Another advantage is that it can measure the refractive index gradient and evaluate the diffusion coefficient from experimental data obtained at various times of diffusion. On the other hand, one disadvantage is that numerical simulations using COMSOL may have issues with numerical resolution and dependence on grid resolution and discretization. Additionally, COMSOL may have limitations in accurately determining the effective diffusion coefficients for solutes passing through native mucus gel, especially for solutes with high molecular mass values. Overall, while COMSOL offers advantages in replicating patterns and evaluating diffusion coefficients, it may have limitations in certain applications and numerical simulations.
