Air and Water Pollution -GlossaryAna P. Morales
A1. absorption: The process of absorption conventionally refers to the intimate contacting of a
mixture of gases with a liquid so that part of one or more of the constituents of the gas will dissolve in the liquid. Such action takes place in all types of wet scrubbers.
absorción
2. adsorption: The molecular forces at the surface of a solid or liquid are in a state of imbalance or unsaturation, due to the fact that the molecules or ions on the surface may not have all their forces satisfied by union with other particles. As a result, solid and liquid surfaces tend to satisfy the residual forces by attracting to and retaining on the surface gases or dissolved substances with which they come in contact. This phenomenon is called adsorption.
adsorción
3. acid rain: some pollutants, particularly SOx and NOx, after a certain time and due to the action of solar light turn into compounds that react with the water contained in the air and form acid. These pollutants, so called acid rain, also become incorporated into snow, rain, and fog, as well as to several dry compounds that react in contact with the ground and the surface of leaves. These acids not only poison lakes and rivers, killing fish and other animals but also corrode metals and paint, and dissolve, indeed, some buildings and stone monuments.
