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 ...

Sorption of albendazole in sediments and soils: Isotherms and kinetics

Chemosphere, 2018
Albendazole is a broad-spectrum anthelmintic drug effective against gastrointestinal parasites in humans and animals. Despite the fact that it has been detected in environment (water, sediment and soil), there is no information on its fate in the environment.

THE ISOPIESTIC METHOD APPLIED TO SORPTION ISOTHERMS

Canadian Journal of Research, 1949
The isopiestic method has been applied to the sorption of carbon tetrachloride and water vapors by activated coconut shell charcoals. The isopiestic charges were found to be linearly related over wide pressure ranges. Isotherms formed by plotting the isopiestic charges of two charcoals one against the other consisted of three linear sections for both ...

Numerical determination of the sorption isotherm for nonisothermal sorption

Computational Mathematics and Modeling, 2009
Two mathematical models of sorption dynamics are considered, one allowing for external diffusion kinetics and the other for internal diffusion kinetics with heat balance. Two inverse problems are investigated for these models and numerical solutions are proposed. The efficiency of the numerical methods is studied in a computer experiment.

Cosolvent effects on sorption isotherm linearity

Journal of Contaminant Hydrology, 2002
Sorption-desorption hysteresis, slow desorption kinetics, and other nonideal phenomena have been attributed to the differing sorptive characteristics of the natural organic polymers associated with soils and sediments. In this study, aqueous and mixed solvent systems were used to investigate the effects of a cosolvent, methanol, on sorption isotherm ...

Thermodynamic Analysis of Moisture Sorption Isotherms

Journal of Pharmaceutical Sciences, 1998
This article illustrates how thermodynamic functions can be calculated from moisture sorption isotherms for water-solid systems. The materials evaluated include the drugs albuterol sulfate and indomethacin, the carbohydrates sucrose, raffinose, and trehalose, and the polymers poly(vinyl pyrrolidone) and microcrystalline cellulose.

Isotherms of Cadmium Sorption Density

Journal of Environmental Quality, 1994
AbstractTo study Cd sorption, 16 soil samples of different chemical soil reactions were taken and analyzed for their physical and chemical properties. Adsorption of ethylene glycol monoethyl ether (EGME) and N2 were determined to establish the specific surface area of the soils.

Isotherm of Strontium Sorption on Clay

Russian Journal of Applied Chemistry, 2003
Sorption of strontium(II) with soil components from model solutions was studied. Limiting sorption of strontium ions, their landing site area, and Langmuir constants were determined.

Modified classification of sorption isotherms

Journal of Food Engineering, 2009
A new equation is developed in this paper which is further used to divide sorption isotherms into classes which are connected to surface water effects and/or solution water effects and their combinations. It is shown that sorption isotherms can be successfully classified using the new equation into three basic classes I, II (most frequent) and III ...

SORPTION ISOTHERMS OF TURKISH DELIGHT

Journal of Food Processing and Preservation, 1998
Moisture sorption isotherms of Turkish delight were determined using the gravimetric static method of saturated salt solutions at 10, 20 and 30C. Isotherms were found to be of type III, typical of high sugar foods. The effect of temperature on moisture content was not significant (P>0.05).
