chemicalabsorbing

Chemicalabsorbing is a nonstandard term that describes the uptake of chemical species by a material through processes that may include bulk absorption as well as chemical interaction with the absorbed substance. In scholarly usage, these mechanisms are more precisely described as absorption (bulk uptake) and chemisorption (chemical bonding to the absorber). The term can also overlap with adsorption when surface phenomena dominate, but chemicalabsorbing is most applicable to cases where chemical reactions or strong chemical interactions occur during uptake.

Absorption refers to the diffusion of molecules into the interior of a liquid or solid without forming persistent chemical bonds. The extent and rate of absorption are governed by solubility, diffusion coefficients, and temperature. Chemisorption, or chemical absorption in a stricter sense, involves the formation of chemical bonds between the absorbed species and active sites in the absorber. This typically yields higher binding energies, greater selectivity, and sometimes irreversible uptake, though many chemisorption processes can be reversed under appropriate conditions to allow regeneration of the material.

Materials used for chemicalabsorbing range from liquids, such as aqueous amine solutions for gas treatment, to solid sorbents including metal oxides, zeolites, activated carbons, and metal–organic frameworks. In many practical systems, chemisorption is exploited for selective capture of reactive species (for example, CO2 or H2S), while physical absorption or adsorption may be used for broad-spectrum removal.

Applications include environmental remediation, gas purification, solvent recovery, and sensor technologies. Key performance factors are capacity, selectivity, operating temperature, regeneration energy, and kinetics, which determine the feasibility and efficiency of chemicalabsorbing in a given process.
