The equilibrium adsorption capacity of an impurity on a given molecular sieve is determined by using isotherms. As an example, Fig. 3 illustrates the isotherms that give the equilibrium adsorption capacity of water on a 4A molecular sieve as functions of temperature and partial pressure of water. At the end of the adsorption phase, the molecular sieve is saturated and no more impurity can be adsorbed.

Effect of Substrate Strain on Adsorption

effect of strain on the adsorption properties of various gases. However, such macroscop-ically applied external forces will inevitably lead to the creation of numerous disloca tions that form easily, especially for metals. On the other hand, external forces that are sufficiently weak not to be relaxed in this way will probably have only small effects,

Introduction - Zakład Zjawisk Międzyfazowych UMCS

The nature of the adsorbent has a profound effect on the adsorption process. The basic feature of a good adsorbent is a large specific surface area . The bigger the surface area,the more molecules are trapped on its surface. Generally, this means that a good adsorbent is very porous.

The effects of water on the adsorption and diffusion of methane in nanopores is studied by ex-situ and in-situ nuclear magnetic resonance. The presence of water suppresses methane adsorption, but this suppression effect is stronger in pores with a diameter of 0.5–3 nm than those with a diameter of 6 nm.

Further, methanol adsorption measurement at 303 K for the crystals with a size of 50 × 50 × 20 nm 3 showed a gate-opening isotherm for the closed-state sample, but an ordinary type-I isotherm for the open-state sample. Similar size-dependent flexibility was also demonstrated for an analogous MOF [Cu 2 (bdc) 2 (bpe)] (bpe = 1,2-bis(4-pyridyl ...


Adsorbent: The material upon whose surface the adsorption takes place is called an adsorbent. Mostly activated carbon is used as an adsorbent Adsorbents are used usually in the form of spherical pellets, rods, moldings, or monoliths with hydrodynamic diameters between 0.5 and 10 mm.

The effects of cells on oxygen transfer in bioreactors ...

The overall effect of cells was to enhance oxygen transfer rates. The physical presence of cells as solid particles was found to retard oxygen transfer, presumably due to the lower oxygen permeability in the cell layer accumulated near the bubble surfaces. Cell respiration and medium modification, on the other hand, enhanced oxygen transfer rates.

Abstract. We also address the effect of cage size, temperature, and sorbate on the guest-induced ring rotation and the adsorption isotherms. The absence of an inflection in the Xe adsorption isotherm in SIFSIX-3-Fe and in the Kr, N 2, and CO 2 adsorption isotherms in SIFSIX-3-Ni suggest that the inflection is highly sensitive to the match between...
