I want to know what adsorbent is. I hope to get a professional answer

As for what adsorbent is, many people think it is a very complicated chemical term. As the name implies, it is a substance that can make active ingredients adhere to the surface of its particles. Adsorbent is very common in daily life, such as activated carbon commonly used in water treatment industry. Adsorbent is an indispensable product in modern industry, which is widely used in oil refining, oil production, water treatment, paper making, textile and other industries. In life, we often come into contact with silica gel products, which are actually an adsorbent. The manufacturing process of adsorbent is very complicated. With the development of chemical materials industry, the adsorption capacity of adsorbents is getting stronger and stronger. For example, UOP has accumulated a number of patented technologies in this respect, and Honeywell UOP adsorbent occupies a large market share. Adsorbent is a chemical, so it must be operated according to the use process. Hope to adopt and give favorable comments.
