Sorptive Properties of Shungite
Inorganic Materials, 2004Ion exchange and sorption on shungite are studied. The results demonstrate that this mineral is capable of sorbing both inorganic cations and anions. Cation exchange predominates in alkaline solutions, and anion exchange, in acidified solutions. Organic acids are sorbed substantially better; the sorption of aromatic acids by shungite is selective.

The sorptive capacity of animal protein
Environmental Toxicology and Chemistry, 2007AbstractPartition coefficients that are used to predict concentrations of hydrophobic organic chemicals in biota (e.g., the bioconcentration factor) often assume that the sorptive capacity of an organism or tissue is adequately represented by its lipid content.

In-port derivatization after sorptive extractions
Journal of Chromatography A, 2013Derivatization is necessary when analysis of polar compounds containing hydroxyl, carboxylic acid, amine or thiol functional groups is accomplished by gas chromatography (GC), in order to improve peak symmetry, peak separation and detector response. Derivatization can be performed off-line in a reaction vessel that is separated from the GC analysis ...

The fields of applicability of headspace sorptive extraction (HSSE) and stir bar sorptive extraction (SBSE) using polydimethylsiloxane (PDMS) as sorbent have been intensively discussed and widely described. One of the limits of sorptive extraction is that PDMS (i.e.

Sorptivity Variation During Infiltration
Transactions of the ASAE, 1985ABSTRACT SORPTIVITY, a constant, as defined by the Philip two-term algebraic infiltration equation, has been of interest to researchers because its development is based on the physical analysis of soil hydraulic properties. This paper presents the mathematical variations of sorptivity under prolonged infiltration time, and thus provides a guide to ...

Sorptive Stress Estimation: An Important Key to the Mechano-Sorptive Effect in Wood
Mechanics of Time-Dependent Materials, 2000The mechano-sorptive effect (MSE) can be classified as a veryinteresting, but not yet completely explained phenomenon of woodbehaviour. We therefore decided to try to discover its most relevantmechanisms, by conducting two independent series of measurements:accurate measurements of bending deflections on small, clear specimensof spruce wood in ...

Transport and separation of proteins by ultrafiltration through sorptive and non-sorptive membranes
Journal of Membrane Science, 1992Abstract Measurement of transmembrane flux and apparent macrosolute rejection during unstirred ultrafiltration of aqueous solutions of bovine serum albumin (BSA) and myoglobin (MYO) and their mixtures have been measured with non-sorptive (regenerated cellulose) and sorptive (polysulfone) membranes of equally rated “cut-off” (30 kDa) as functions of ...

Silicone rod and silicone tube sorptive extraction
Journal of Chromatography A, 2010This review focuses on the applications of silicone in the form of tubes or rods for sorptive extraction of organic compounds as sample preparation method in combination with various chromatographic techniques. Silicone rods (SRs) and silicone tubes (STs) have the advantage of being inexpensive, flexible and robust. SRs and STs with different sizes and

Sorptivity calculation for arbitrary diffusivity
Transport in Porous Media, 1994An estimate of the sorptivity that requires only the knowledge of simple integrals of the soil-water diffusivity weighted by a power of the water content is present. The result is checked systematically for diffusivity functions with very different behaviours: power law, exponential and the two Fujita diffusivities.
