adsorbent

[ad′sȯr·bənt]
(chemistry)
A solid or liquid that adsorbs other substances; for example, charcoal, silica, metals, water, and mercury.

Adsorbent

Material that is capable of binding and collecting substances or particles on its surface without chemically altering them.

adsorbent

A material (such as activated charcoal) which has the ability to extract certain substances from gases, liquids, or solids by causing the substances to adhere to its internal surface without changing the adsorbent physically or chemically.

Molecular sieves are the largest segment of adsorbents that have very small pores of precise and uniform size.
4 The effect of adsorbent quantity on the efficiency of copper removal:
When the pressure drops, the adsorbent deflates and releases the C[O.
Fixed bed dynamics are describing by a set of convection-diffusion equations, coupled with source terms due to adsorption and diffusion inside adsorbent particles.
As the surface adsorption sites become exhausted, the uptake rate is controlled by the rate at which the adsorbate is transported from the exterior to the interior sites of the adsorbent particles (Bulut, Tez 2007).
This behavior can be attributed to the relationship between the effective specific surface area of the adsorbent particles and their size.
The adsorbent can then be regenerated and reused after being conditioned with potassium hydroxide.
Because there is no chemical binding, the EVA does not act only as support of the adsorbent but also as a dispersant, and this makes it easy to recover the sheet-like adsorbent compared to a fine powder of lignin, for example.
Adsorption studies were carried out at room temperature with initial concentration range from 5 to 100 ppm, adsorbent dosage range from 1 to 6 gm and size of the adsorbent ranges from 500-150 [micro]m.
However, the success of the removal of mercaptans and like depends on the development of a highly selective adsorbent with a high sulphur capacity, because the currently available commercial adsorbents are not suitable for this application.
The adsorbent allows us to extract previously inaccessible proteins from our waste stream," commented Marco Giuseppin, Director R&D of Solanic.
