Adsorbents can be used in both air and water pollution control.
In water pollution they are principally used in the collection of trace oil slicks from surface waters as a polishing step in cleaning up oil spills. Absorbents can also be used in heavier oil slicks to hold the oil on the surface as it is being vacuumed up.
In air pollution absorbents can be used to remove traces of gases or hydrocarbons from air flows in small treatment systems (air intakes over gluing tables etc.) or in air filtration masks to prevent workers from inhaling gases or vapours.

Factors influencing on sorption?
The following factors influences the sorption- 1- temperature of both gas and adsorbent. 2- the chemical nature of gas and adsorbent. 3- the microscopic roughness of the surfaceof adsorbent. 4- the incident flux of molecules. 5-surface to volume ratio of the adsorbent.
How do you activate eggshell as adsorbent?
To activate eggshells as an adsorbent, you can start by washing and drying them thoroughly. Then, grind the eggshells into a powder using a blender or mortar and pestle. Next, heat the powdered eggshells in an oven at a temperature of around 350°F (177°C) for about 30 minutes. This process helps to activate the adsorbent properties of the eggshells and make them more effective in adsorbing substances.
What is the difference between adsorbent and adsorbate?
adsorbent is a substance that is usually porous in nature with high surface area that can adsorb substances onto its surface with the help of intermolecular forces while the adsorbate is a substance that is adsorb on a surface of another substance.
Why silica used in chromatography columns?
because silica is the best adsorbent used in column chromatography it almost supoort polar and non polar substances which areto be seprated....another reason is that it also seprate those substances which has intermediate polarities......
What is the function of pump in HPLC?
A high-performance liquid chromatography, or HPLC, refers to a technique in analytic chemistry that is used to separate the components in a mixture. The pump in HPLC passes a pressurized liquid solvent that contains the sample mixture through a column filled with a solid adsorbent material.
How many types of adsorbent?

How do you calculate molecular weight of a compound from its langmuir isotherm?
The monolayer capacity of the adsorbent is equal to number of moles of adsorption sites present on one gram of sample. The Langmuir and BET isotherms may be used to find th monolayer capacity of the adsorbent. Thus on taking the reciprocal of the monolayer capacity, one can find the molecular weight of the adsorbent.

What does adsorb mean?
An adsorbent is the solid or liquid in the process of adsorption on which the adsorbate accumulates.
Can carbon be an adsorbent?
Yes, frequently; follow the link http://en.wikipedia.org/wiki/Active_carbon.
Is there any adsorbent which can adsorb carbon di oxide?
Not easily, although it is soluble in lime-water.
Is wood adsorbent?
Yes, depending of they type of wood, it may differ in absorbency amount and speed
