Wanna know what are the top 6 applications of adsorption in various industries? If yes, then you are at the right place at the very right time. But before going ahead, let me tell you what is adsorption anyway? Adsorption is a fascinating scientific phenomenon that refers to the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.

In other words, it is a process during which a substance only adheres or adsorbs to the surface of the other substance, hence, also a surface phenomenon. The substance that gets adsorbed is known as Adsorbate. On the flip side, the substance that adsorbs is known as Adsorbent.

This process plays a vital role in our daily lives, even though we may not be aware of it. From the air we breathe to the industrial products we use, adsorption has a wide range of applications due to its ability to separate, purify, and enhance materials. In this exclusive article, we will explore 6 diverse examples of adsorption in everyday life, shedding light on its practical applications and importance. Therefore, without wasting any more time, let’s dive right in…!!!

Top 6 Applications of Adsorption in Various Industries

  • Dehumidifier
  • Odor Control
  • Catalysis
  • Chromatography
  • Silica Get Packets
  • Air Purifier


The very first one in my list of top 6 applications of adsorption in various industries is Dehumidifier. The process of adsorption is fundamental to the functioning of dehumidifiers. Adsorbent materials, such as zeolites, attract and retain moisture from the air, effectively reducing humidity levels.

To put it differently, Adsorption aids dehumidifiers by removing excess moisture from the air. Using adsorbent materials like silica gel or activated carbon, dehumidifiers attract and trap moisture molecules. Through desorption and regeneration, they release moisture to the outer environment and maintain a comfortable indoor environment.

Odor Control

Adsorption plays a crucial role in odor control by effectively trapping and neutralizing unpleasant odors. When adsorbent materials, such as activated carbon, come into contact with odorous compounds, they chemically or physically bond with the molecules, preventing them from being released into the air. This process effectively reduces and eliminates foul smells.

In other words, these substances adsorb odor-causing molecules, reducing unpleasant smells in confined spaces. From shoe deodorizers to refrigerator fresheners, even the deodorant you use, activated carbon effectively adsorbs and neutralizes foul odors, keeping our surroundings fresh and pleasant.


Adsorption plays a crucial role in enhancing the performance of certain catalysts in chemical reactions by adsorbing reactant molecules onto their surface. Catalysts facilitate the formation of product molecules, expediting the overall reaction. It involves the accumulation of reactant molecules on the catalyst’s surface, leading to increased contact and interaction with the catalyst. This promotes the formation of activated species, such as surface intermediates, which can undergo desired chemical transformations more easily.

To put it differently, adsorption helps catalysts by improving the efficiency of reactant activation, facilitating the breaking and formation of chemical bonds, and providing a favorable environment for reaction pathways. Additionally, adsorption can increase the surface area available for catalytic reactions, enhancing the catalyst’s overall activity.


The next one on my list of the top 6 applications of adsorption in real life is the process of chromatography. Adsorption is one of the fundamental principles involved in the process of chromatography used in analytical chemistry. It involves the separation and analysis of different components in a mixture based on their affinity for an adsorbent material.

Different compounds adsorb to various extents on stationary phases, enabling their separation and identification. Adsorption enables the selective retention and separation of different compounds within a mixture, allowing for the analysis, identification, and purification of substances in various scientific and industrial applications such as pharmaceutical analysis, environmental monitoring, forensic science, etc.

Silica Get Packets

Ever wondered why you find silica gel packets every time you buy something you newly purchased? Because small silica gel packets found in various packaged goods serve an essential adsorption purpose. These small packets utilize adsorption to remove moisture from their surrounding environment.

Silica gel, a porous and highly adsorbent form of silicon dioxide, has a large surface area that attracts and retains water molecules through physical adsorption. As a result, these packets help maintain the quality and freshness of products by preventing moisture-related damage, such as mold growth, spoilage, mildew, corrosion, etc, in various products and storage containers.

Air Purifier

We all know how much air is essential for the survival of all the beings on planet Earth. Be it humans, animals, or even amoeba, all living creatures cannot survive without the availability of fresh air on Mother Earth. So, that is why last but not least one on my list of top 6 applications of adsorption in everyday life is Air Purifiers.

Air purifiers or air fresheners use adsorption to neutralize odors and enhance the fragrance in the air. Adsorbents like zeolites or activated carbon capture airborne pollutants, such as volatile organic compounds (VOCs) and odors, promoting cleaner and healthier air indoors. To sum up, Adsorption helps improve indoor air quality, reducing the risk of respiratory issues and allergies.

Some Other Adsorption Examples in Daily Life

Apart from the above-mentioned ones, I am also mentioning a few here.

  • Water Purifiers
  • Gas Mask
  • Drug Delivery Systems
  • Inkjet Printers
  • Soil Remediation
  • Gas Storage
  • Blood Purification
  • Dental Care, etc.

I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics. Right now I am a loner (as ever) and a Physics blogger too. My sole future goal is to do a Ph.D. in theoretical physics, especially in the field of cosmology. Because in my view, every aspect of physics comes within the range of cosmology. And I love traveling, especially the Sole one.
