Definition: The term "adsorption" in English refers to a process by which substances absorb water, causing them to swell or displace other substances. This occurs when an insoluble substance (such as a solvent) binds to another substance (the solute), causing it to dissolve and become more permeable. Here’s a detailed definition of "adsorption": Adhesion is the physical interaction between two solid surfaces that allows the surface of one surface to come into contact with an area on the other. Adsorption occurs when there are attractive forces between the two surfaces, allowing molecules or particles on one surface to move and bind to the surface of the other. In the context of chemical adsorption, a material is adsorbed when it comes in contact with a solvent that is able to dissolve the substance it is being adsorbed upon. This means that the substance becomes more permeable than previously, allowing it to pass through and reach another surface where it can be isolated or used. Adhesion also refers to the interaction of two substances (often liquids) on one side of an interface with a solid surface on the other. It is important in the design of adsorbents, materials that are capable of adsorbing onto surfaces without causing them to chemically bond to them directly. In summary, "adsorption" describes the physical process by which a substance (often water) binds to another substance (the solvent) and causes it to displace it, allowing it to interact with an area on the surface. This can be important in applications where the substances need to maintain their purity or ability to dissolve others.
