Eroaaadsorptio

Eroaaadsorptio appears to be a term that may refer to adsorption, the process by which atoms, ions, or molecules from a phase (gas or liquid) adhere to the surface of a solid or liquid. The exact spelling and usage of eroaaadsorptio are not standard in English-language chemical literature, and the term may reflect a transliteration, a regional spelling, or a typographical variation of adsorption in some languages. In general, adsorption describes interfacial accumulation rather than a chemical transformation of the adsorbate.

Adsorption can be classified as physical (physisorption) or chemical (chemisorption). Physisorption involves weak van der Waals forces and is typically reversible, with adsorption increasing at lower temperatures and higher surface areas. Chemisorption involves the formation of chemical bonds and is often more specific, stronger, and sometimes irreversible. Adsorption may occur as monolayer or multilayer coverage, depending on the surface and the adsorbate, and is influenced by surface structure, pore size, and temperature.

Isotherms model how adsorption varies with pressure or concentration at a constant temperature. The Langmuir model describes monolayer adsorption on a homogeneous surface, while the Freundlich model is empirical for heterogeneous surfaces. The Brunauer–Emmett–Teller (BET) theory extends these ideas to multilayer adsorption and surface area determination. Thermodynamic and kinetic analyses yield parameters such as adsorption enthalpy, entropy, and rate constants, informing process efficiency and design.

Applications span water and air purification, catalysis, sensors, and separation technologies, with materials including activated carbon, zeolites, silica, and metal oxides. See also adsorption isotherms, physisorption, chemisorption, and surface science.
