A more common definition is that "Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enter into the bulk phase (gas, liquid or solid) of the material in which it is taken up." A more general term is sorption, which covers absorption, adsorption, and ion exchange. Absorption ...
Absorption "the incorporation of a substance in one state into another of a different state" [1] (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid); Adsorption The physical adherence or bonding of ions and molecules onto the surface of another phase (e.g., reagents adsorbed to a solid catalyst surface); Ion exchange
This is termed "absorption." A material which absorbs a wave's energy, either in transmission or reflection, is characterized by a refractive index which is complex. The amount of absorption will generally depend on the frequency (wavelength) of the wave, which, for instance, explains why objects may appear colored.
The term absorption refers to the physical process of absorbing light, while absorbance does not always measure only absorption; it may measure attenuation (of transmitted radiant power) caused by absorption, as well as reflection, scattering, and other physical processes. Sometimes the term "attenuance" or "experimental absorbance" is used to ...
In electronic absorption, the frequency of the incoming light wave is at or near the energy levels of the electrons within the atoms that compose the substance. In this case, the electrons will absorb the energy of the light wave and increase their energy state, often moving outward from the nucleus of the atom into an outer shell or orbital .
Assimilative capacity is the ability for pollutants to be absorbed by an environment without detrimental effects to the environment or those who use of it. [1] Natural absorption into an environment is achieved through dilution, dispersion and removal through chemical or biological processes. [1]
Spectral hemispherical absorptance in frequency and spectral hemispherical absorptance in wavelength of a surface, denoted A ν and A λ respectively, are defined as [2] =,,, =,,,
Absorption (economics), the total demand of an economy for goods and services both from within and without Absorption (logic), one of the rules of inference Absorption costing, or total absorption costing, a method for appraising or valuing a firm's total inventory by including all the manufacturing costs incurred to produce those goods
