The effects of anion sorption on sorption and leaching of cadmium
Australian Journal of Soil Research, 1999The effect of chloride, sulfate, nitrate, and phosphate anions on the sorption and leaching of cadmium was examined in 2 soils (Manawatu silt loam and Egmont clay loam) which differ in their variable charge components. There was a larger sorption of cadmium in the presence of phosphate than in the presence of sulfate, nitrate, and chloride, and the ...

Intraparticle Sorption and Desorption of Antibiotics
Journal of Hazardous Materials, 2023Intraparticle domains are the critical locations for storing contaminants and retarding contaminant transport in subsurface environments. While the kinetics and extent of antibiotics sorption and desorption in subsurface materials have been extensively studied, their behaviors in intraparticle domains have not been well understood.

Water vapor adsorption/desorption isotherm studies were performed on high volatile bituminous B coal and lignite to investigate the behavior of water on coal. The characterization of water sorption was studied by kinetic and equilibrium data, at a temperature of 298 K and a relative vapor pressure up to 0.95.

Siderophores are low molecular weight organic ligands exuded by some aerobic organisms and plants to acquire Fe under Fe-limited conditions. The hydroxamate siderophores may sorb to aluminosilicate clays through a variety of mechanisms depending upon the nature of the clay and of the siderophore along with solution conditions such as pH, ionic strength,

Sorption, sorption kinetics and diffusion of pyridine in zeolites
Microporous and Mesoporous Materials, 1998Abstract In situ FTIR spectroscopy was used to monitor the sorption and desorption kinetics of pyridine into and out of microporous materials such as mordenite, ZSM-5 and silicalite. A previously described experimental technique and method of evaluation, which had been successfully used to study sorption and sorption kinetics of aromatics in H-ZSM-5,

This work presents a simple solution for the diffuse double layer model, applicable to calculation of surface speciation as well as to simulation of ionic adsorption within the diffuse layer of solution in arbitrary salt media. Based on Poisson-Boltzmann equation, the Gaines-Thomas selectivity coefficient for uni-bivalent exchange on clay, K(GT)(Me(2+)/

Sorption Isotherms and Heats of Sorption for Fruit Jams
1994Water sorption isotherms at three different temperatures for two different brands of “marmelada” quince jam and four brands of peach jam were measured, using a static equilibration method. Results obtained showed that the typical high sugar content of these products leads to an inversion of the usual temperature-dependence of water sorption isotherms ...

Azimsulfuron Sorption−Desorption on Soil
Journal of Agricultural and Food Chemistry, 2004The sorption and desorption of the herbicide azimsulfuron, N-[[(4-dimethoxypyrimidin-2-yl)amino]carbonyl]1-methyl-4-(2-methyl-2H-tetrazole-5-yl)1H-pyrazole-5-sulfonamide, were studied using five soils. Sorption isotherms conformed to the Freundlich equation. It was found that pH is the main factor influencing the sorption and that the sorption on soils

The diffusion and sorption of water in zeolites—I. Sorption
Journal of Physics and Chemistry of Solids, 1961Abstract Equilibrium sorption measurements have been made for D2O and H2O in the crystalline zeolites chabazite, gmelinite and heulandite, at relative coverages greater than θ = 0.85. The water contents, the shape of the isotherms, the isosteric heats and the partial molar entropies are almost identical for H2O in chabazite and gmelinite; in ...

Theory of sorption chromatography
Journal of Chromatography A, 1965Abstract The earlier theory of partition chromatography by the author has been extended to sorption chromatography by incorporating a sorption term for solute interaction with the stationary phase of a chromatographic column. A procedure for the numerical solution of the problem is indicated.
