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.

On application of an isothermal sorption microcalorimeter

Thermochimica Acta, 2001
A wide scope of application of a novel isothermal sorption microcalorimeter is presented. With the technique, it is possible to simultaneously and independently in one experiment obtain the sorption isotherm of a sample along with the corresponding differential enthalpies of sorption.

Sorption isotherms of tapioca flour

International Journal of Food Science & Technology, 2012
SummaryThe adsorption and desorption isotherms of tapioca flour was performed in the range of water activity (aw) from 0.22 to 0.92 at 25 °C, and the applicability of six mathematical models in data prediction was evaluated. The tapioca flour presented Type II isotherm (sigmoid), and the hysteresis effect was not observed.

The sorption isotherms of maize meal

International Journal of Food Science & Technology, 1969
Summary. The equilibrium moisture contents of the three main grades of South African maize meal over a range of 1.4‐90.7% relative humidity (r.h.) were determined at 30°C. It was found that the fat content of maize meal influenced the moisture content at equilibrium, i.e.

Thermodynamics and Modeling of Sorption Isotherms

Chemie Ingenieur Technik, 2016
AbstractAn extended version of the thermodynamic computation model for sorption isotherms and capillary condensation is introduced. With the combination of the excess surface work (ESW) and disjoining pressure approach sorption isotherms for various pore size distributions of cylindrical and slit‐like mesopores are successfully modeled.
