Acifluorfen Sorption and Sorption Kinetics in Soil

Journal of Agricultural and Food Chemistry, 1997
Factors which influence kinetics of sorption for acifluorfen, a postemergence herbicide, in soil were evaluated. Twelve soils of varying characteristics were used in this study. Sorption kinetics experiments with 5.86 μM 14 C-labeled (19.6 Bq mL -1 ) acifluorfen were conducted for equilibration times up to 96 h.

Sorption in zeolites—III. Binary sorption

Chemical Engineering Science, 1986
Abstract Binary and multicomponent diffusion in zeolites is of considerable practical relevance. However, the nature of flux equations applicable to such systems and the relationship between the binary diffusion coefficients and intrinsic diffusion coefficients is not well understood.

Sorption isotherms and heat of sorption of pineapple

Journal of Food Engineering, 2001
Sorption isotherms of pineapple were determined at 20°C, 30°C, 40°C and 50°C temperatures by using dynamic method. Six two-parameter and one three-parameter isotherm models were selected to fit the observed data, and the modified BET model was found to be the best-fitted model for pineapple.

Phosphate Sorption by Soils: II. Sorption Measurement Technique

Soil Science Society of America Journal, 1984
Abstract A computer‐controlled apparatus has been developed for measurement of P sorption by soils. A solution containing P is constantly pumped from a vessel through a soil column and back to the vessel again.

Sorption of antibiotics to biofilm

Water Research, 2011
Using a continuous-flow rotating annular bioreactor, sorption of three selected antibiotics (sulfamethoxazole (SMX), ciprofloxacin (CIP), and erythromycin (ERY)) to bacterial biofilm was investigated. CIP had the greatest biofilm partition coefficient (K(oc) = 92,000 ± 10,000 L/kg) followed by ERY (K(oc) = 6000 ± 1000 L/kg) and then SMX (K(oc) = 4000 ±

The effects of anion sorption on sorption and leaching of cadmium

Australian Journal of Soil Research, 1999
The 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, 2023
Intraparticle 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 sorption on coals

Journal of Colloid and Interface Science, 2010
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.

Siderophore sorption to clays

BioMetals, 2009
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 Isotherms and Heats of Sorption for Fruit Jams

1994
Water 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 ...
