ABSTRACT Crude wheat gliadin from acetic acid solution showed lower water sorption by pulse and frontal Inverse Gas Chromatography methods as compared to a static method but the pulse data for a highly purified Ponca wheat gliadin from ethanol agreed with static data for crude gliadin.

Water-Sorption Properties of Tablet Disintegrants
Journal of Pharmaceutical Sciences, 1975The water-sorption properties of four tablet disintegrants, starch, sodium carboxymethylcellulose, sodium starch glycolate, and a cation-exchange resin, were examined in the form of powders and in compressed tablets prepared from calcium phosphate dibasic dihydrate.

Water vapor sorption of hyaluronic acid
Biochimica et Biophysica Acta (BBA) - General Subjects, 1970Abstract Water vapor sorption isotherms were obtained for three samples of hyaluronic acid. Reproducible isotherms were obtained for all sodium and potassium hyaluronates while the acid form of one hyaluronic acid sample exhibited increased sorptive capacity for three successive sorption isotherms. The values of Brunauer-Emmett-Teller, hysteresis and

Antimony sorption at gibbsite–water interface
Chemosphere, 2011Antimony (Sb) is extensively used in flame retardants, lead-acid batteries, solder, cable coverings, ammunition, fireworks, ceramic and porcelain glazes and semiconductors. However, the geochemical fate of antimony (Sb) remained largely unexplored. Among the different Sb species, Sb (V) is the dominant form in the soil environment in a very wide redox ...

Water sorption in cellulose‐based hydrogels
Journal of Applied Polymer Science, 1996Sorption of distilled water in a cellulose-based hydrogel is presented. The examined system is based on a mixture of sodium salt of carboxymethylcellulose and hydroxyethylcellulose, crosslinked with divinilsulphone. The effect of chemical composition, manufacturing procedures, as well as desiccation protocols on equilibrium water uptake was ...

Environmental Science and Technology, 2021
Sorption-based atmospheric water harvesting (SAWH), which uses sorbents to capture water vapor from the air and low-grade energy to produce fresh liquid water, has been recognized as a promising strategy for decentralized water supply in arid areas. This

Water sorption in a dextran gel
Carbohydrate Research, 1975The state of adsorbed water in a dextran gel has been investigated by near-infrared gravimetric-adsoprtion techniques. Water-vapor adsorption (desorption) isotherms at three temperatures are reported. The calculated sorption heats are found to be markedly temperature-dependent as well as dependent on the coverage.

Water sorption in poly(ammonium sulfopropylbetaines). II. Sorption isotherms
Journal of Polymer Science Part B: Polymer Physics, 1992AbstractWater sorption by four amorphous acrylic and methacrylic poly(zwitterions) bearing ammonium sulfopropylbetaine side groups () was studied at a constant temperature of 23°C and over a broad range of water activity (0.14‐0.90). Whatever the physical state of the hydrated polymer, glassy or viscoelastic, water diffusion is Fickian (average ...

Water Sorption Thermodynamics in Polymer Matrices
2013Water sorption is a key issue in assessing the durability of polymer matrix composites. In fact absorbed water can adversely affect mechanical properties of the matrix and fibre-matrix interface integrity. In this contribution the general issue of water sorption thermodynamics in polymers is addressed from the experimental and theoretical point of view.
