Solid Sorption. A material such as silica gel or activated aluminium through which the moisture-laden gas is passed achieves solid sorption see Fig. 9,18. The mass transfer that takes place depends on the relative conditions of the chemical and the air conditions. As the material becomes saturated, hearing the bed and applying a vacuum to it will reverse the process. Once sufficient water is removed from the material, it can be reused. 

Correlations between solubility, liquid-liquid partition, and solid sorption have been shown to be insufficient proof of a partition process and do not allow predictions to be applied to all diverse groups of organic pollutants and solid phases. 

The conversion to solid sorption media from liquid absorption solutions for collection of gases and vapors is a continuing process. The solid sorbent sampling tube is a small device, easily manipulated, and not prone to lose its contents when being used under awkward sampling conditions or during shipping. These physical factors can improve the accuracy of the final result. 

Returning to the sorption observations (Fig. 9.7), as the mass fraction of organic carbon, foc, present in the solids approaches zero, the Kid values for both compounds become very small. Even at very lowy values. Q.,f0C = 0.001 kg oc-kg 1 solid), sorption to the organic components of a natural sorbent may still be the dominant mechanism (see Chapter 11).

By irradiating a solid with photons, it is possible to alter in a well controlled way the occupation of the bond orbitals in the surface of the solid. This procedure enables us to influence surface migrations of atoms of the solid, sorption reactions and catalytic reactions, and to reveal the bond changes fundamental to any surface reaction. Several sorption processes have been investigated and may be interpreted to a certain extent. The interpretation of catalytic processes, however, is still too general. One problem in particular remains unsolved whether the adsorption states studied so far are identical with the unstable short-lived transition states which occur in catalytic reactions.

Sorption is the process where a sorbate binds to a sorbent. In this discussion, the sorbate is the organic contaminant and the sorbent is the aquifer solid. Sorption has a large impact on the rate at which a contaminant is transported, as well as on its ultimate fate. Since sorbed contaminant is immobile, the sorption process retards contaminant transport. Also, since sorbed contaminant is frequently assumed to be unavailable for microbial degradation [5-7], sorption slows the rate at which a contaminant is biodegraded in the subsurface.

Mobility and transport of radionuclides in the geosphere are influenced markedly by their interaction with solids. Migration is retarded, or even stopped, if the interaction is strong, in particular if the radionuclides are incorporated into the solids. Sorption of radionuclides on solids has been investigated extensively for materials in the neighbourhood of planned high-level waste repositories. 

In this paper we consider SHP as a combination of a loop heat pipe (LHP) and ammonia/ (active carbon fiber -I- chemicals) solid sorption cooler. Such system extends the limits of two-phase thermal control and ensures successful mode of electronic components cooling even in very harsh environmental conditions (ambient temperature 40 °C, or more) and ensures a deep cooling of space sensors down to the triple point of the hydrogen.

Taking into account the physicochemical similarities between complexation and adsorption reaction mechanisms, one can conclude that divalent copper ions are the most strongly sorbing of the various trace metals. This species can sorb onto both inorganic and organic solids. Sorption of copper onto oxides and clays has been investigated extensively (see Box 1). 

So the maximum temperature rise in a gas-solid sorption can reach 25 °C.
