The accumulation of gases, liquids, or solutes on the surface of a solid or liquid. (noun) Define absorption. absorption synonyms, absorption pronunciation, absorption translation, English dictionary definition of absorption. n. 1. The act or process of absorbing or the condition of being absorbed.
Adsorption is the process of adhesion of molecules of liquid or gases onto the surface of a solid particle. Phenomenon: Absorption is a bulk phenomenon where molecules of absorbate enter into the absorbent. Adsorption is a surface phenomenon where the molecules simply attach to the surface of the adsorbent. Principle

Depending on the nature of the absorbent/adsorbent-to-surface bond, there are a multitude of mechanisms for desorption. The surface bond of a sorbant can be cleaved thermally, through chemical reactions or by radiation, all which may result in desorption of the species. Adsorption and absorption, the Latin term referring to absorption in the bulk of the solid, are subsumed under the general term sorption. The phenomenon of adsorption first came under study in the late 18th century by Scheele (1773), though there is no question that adsorption had been used by humanity in practical activities from time immemorial. 2006-06-07 · Adsorption, the binding of molecules or particles to a surface, must be distinguished from absorption, the filling of pores in a solid. The binding to the surface is usually weak and reversible.
[Production Facilities, Enhanced Oil Recovery]. The property of some solids and liquids to attract a liquid or a gas to their surfaces.

The mean yield class for Sitka spruce in Great Britain is 14 m3 ha–1 year–1, for Sitka spruce averaged for adsorption and desorption (after Ahmet et al., 2000). the removal of radionuclides from lakes by adsorption on sediments migration of uranium,and an increase in pH - meaning an increase in.

A Critical Short Review of Equilibrium and Kinetic Adsorption Models for Adsorption is defined as the enrichment of material or increase in the density of the
In this work, we introduce the rate of adsorption as a means to systematically quantify the extent, and identify the underlying causes, of history dependence. Kd is defined as the ratio of the equilibrium concentrations of a substance adsorbed onto a solid sorbent to that dissolved in a liquid phase.
