Adsorption is the process by which a substance (solid or liquid) is attracted and held onto another substance (also solid or liquid) due to forces like dipole-dipole interaction. The process is reversible, meaning that the adsorbed substance can be desorbed back into its original state.
Adsorption is a crucial phenomenon in many areas of chemistry, such as biology, environmental science, and materials science. In biology, adsorption is responsible for the absorption of nutrients, drugs, and toxins by cells. In environmental science, adsorption plays a vital role in the removal of contaminants from water and soil. In materials science, adsorption is used to improve the performance of materials in various applications, such as in water purification and catalysis.
Adsorption can be represented graphically with a solid-line arrow pointing from the adsorbate to the adsorbent. The adsorbate is the substance that is attracted to the adsorbent, and the adsorbent is the substance that attracts the adsorbate. The forces that hold the adsorbate in place are typically dipole-dipole interactions, which are caused by the temporary dipoles induced in the adsorbent due to the polarity of the adsorbate
