Exempel på hur man kan använda ADSORPTION i en mening

• His wide-ranging research in physical science included chemical kinetics, x-ray diffraction, and adsorption of gases.
• Electrode potential appears at the interface between an electrode and electrolyte due to the transfer of charged species across the interface, specific adsorption of ions at the interface, and specific adsorption/orientation of polar molecules, including those of the solvent.
• Chemisorption is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate.
• Physisorption, also called physical adsorption, is a process in which the electronic structure of the atom or molecule is barely perturbed upon adsorption.
• Sorption isotherm a curve giving the functional relationship between adsorbate and adsorbent in a constant-temperature adsorption process.
• While adsorption does often precede absorption, which involves the transfer of the absorbate into the volume of the absorbent material, alternatively, adsorption is distinctly a surface phenomenon, wherein the adsorbate does not penetrate through the material surface and into the bulk of the adsorbent.
• For adsorption that occurs on specific sites (Langmuir adsorption isotherm) the most common standard state is a relative coverage of , as this choice results in a cancellation of the configurational entropy term and is also consistent with neglecting to include the standard state (which is a common error).
• It can be used to characterize a generic biochemical reaction, in the same way that the Langmuir equation can be used to model generic adsorption of biomolecular species.
• During the final two decades of his work at Messiah, up to the age of 104, he worked on experiments involving adsorption of toxic metals by plant material and the use of living plants for purifying the environment (phytoremediation).
• Activated carbon is used in methane and hydrogen storage, air purification, capacitive deionization, supercapacitive swing adsorption, solvent recovery, decaffeination, gold purification, metal extraction, water purification, medicine, sewage treatment, air filters in respirators, filters in compressed air, teeth whitening, production of hydrogen chloride, edible electronics, and many other applications.
• The centrality of his thesis focused towards the research on the Freundlich (or classical) adsorption isotherm, and Zeldovich discovered the theoretical foundation of this empirical observation.
• However, subsequent studies (including a comprehensive 2005 meta-study) revealed the stomach purging produced by ipecac to be far less effective at lowering total body poison concentrations than the adsorption effect of oral activated charcoal (which is effective through the entire gastrointestinal tract and is often coupled with whole bowel irrigation).
• In 1925, Semyonov, together with Yakov Frenkel, studied kinetics of condensation and adsorption of vapors.
• Frumkin has developed the Frumkin isotherm, an extension of the Langmuir isotherm in describing certain adsorption phenomena.
• PPD is used extensively as a cross-linking agent in the formation of COFs (covalent organic frameworks), which have a number of applications in dyes and aromatic compounds adsorption.
• Filters use sieving, adsorption, ion exchanges, biofilms and other processes to remove unwanted substances from water.
• A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles.
• Nucleation can be modeled by characterizing surface process of adsorption, desorption, and surface diffusion.
• The Langmuir-Hinshelwood process in heterogeneous catalysis, in which the adsorption of the reactants on the surface is the rate-limiting step, is named after him.
• From then to 1935 he published a number of papers on diffusion and adsorption in naturally occurring base-exchanging zeolites, and these studies continued during a year's visit to Hugh Stott Taylor's laboratory in Princeton University with support of a Rockefeller Foundation fellowship.
