Sorbent[edit]

A sorbent is a material used to absorb or adsorb liquids or gases. Sorbents are commonly used in various applications, including environmental cleanup, industrial processes, and personal protective equipment such as gas masks.

Types of Sorbents[edit]

Sorbents can be classified into three main types based on their mechanism of action:

Absorbents[edit]

Absorbents are materials that take in a liquid or gas into their structure, causing the sorbent to swell. This process involves the penetration of the substance into the bulk of the absorbent material. Common examples include sponges and certain polymers.

Adsorbents[edit]

Adsorbents are materials that capture substances on their surface. This process involves the adhesion of molecules onto the surface of the adsorbent. Activated carbon is a well-known adsorbent used in air and water purification.

Chemisorbents[edit]

Chemisorbents involve a chemical reaction between the sorbent and the substance being captured. This type of sorption is often irreversible and is used in applications where a permanent bond is desired.

Applications of Sorbents[edit]

Sorbents are used in a variety of applications, including:

Environmental Cleanup[edit]

In environmental cleanup, sorbents are used to remove oil spills, hazardous chemicals, and other pollutants from water and soil. They are essential in mitigating the impact of environmental disasters.

Industrial Processes[edit]

In industrial settings, sorbents are used to capture and remove unwanted substances from gases and liquids. This includes the removal of impurities from chemical processes and the purification of air and water.

Personal Protective Equipment[edit]

Sorbents are a critical component of personal protective equipment, such as gas masks. In these applications, sorbents are used to filter out harmful gases and vapors, protecting the wearer from inhaling toxic substances.

Mechanism of Sorption[edit]

The mechanism of sorption can vary depending on the type of sorbent and the substance being captured. In general, sorption involves the interaction between the sorbent material and the substance, which can be physical or chemical in nature.

Physical Sorption[edit]

Physical sorption, or physisorption, involves weak van der Waals forces between the sorbent and the substance. This type of sorption is typically reversible and does not involve a chemical reaction.

Chemical Sorption[edit]

Chemical sorption, or chemisorption, involves the formation of a chemical bond between the sorbent and the substance. This process is often irreversible and results in a stronger interaction compared to physical sorption.

+== Sorbent ==
-A '''sorbent''' is a material used to absorb or adsorb liquids or gases. The process of absorption or adsorption occurs when atoms, ions, or molecules from a substance (it could be gas, liquid, or dissolved solid) adhere to a surface of the adsorbent. Sorbents are used in a wide range of applications, from environmental cleanup to industrial processes and healthcare.
