Adsorption The process by which filter media attracts unwanted molecules to its surface via a chemical charge.
Adventitious root A root which develops from the node of a stem or similar organ, such as a Rhizome, Stolan or runner.
adsorption
If absorption is when a substance is soaked up by another - think of a sponge - then adsorption would be if the sponge accumulated liquid around itself to form an outer membrane. Chemical filter media removes waste by adsorbing it.
Adsorption The process by which organic molecules are chemically bonded onta a surface of a medium, such as activated carbon.

Adsorption takes place due to intramolecular attraction between the carbon surface and the substance that is being adsorbed.
Poly adsorption pads and disks are also effective chemical filtrants available. These are very effective in targeting certain chemical components (ie, phosphate, nitrate, copper) that are harmful to the reef.
Molecular Adsorption Pads: Polyester pads that have been chemically treated to absorb certain substances from the water. This form of chemical filtration is placed in a canister or power filter.
Pressure Swing Adsorption
The process of separating oxygen and nitrogen gas. The process uses carbon molecular sieves, which are substances with precisely sized passages.
Examples are protein skimmers and any filter containing chemical media such as activated carbon, molecular adsorption pads, or resins. chiller A device which makes aquarium water cooler.
nutrient cations for plants but at low pH they may hold anions] * Not listed in the table but also of importance are some amorphous minerals of volcanic origin (allophane) which can have both a high CEC as well as considerable anion adsorption ...

The first is adsorption. Static forces will attract particles, adsorbing them onto the surface of the carbon. Bacteria that settle on the carbon surface will further consume the waste. Another process is the diffusion of gases.
These pellets contain microscopic caverns that are the right size to trap certain molecules or ions (called adsorption as opposed to absorption). After a period of 3- 6 months or so, the carbon becomes ineffective.
Important cations in the cation exchange complex in order of adsorption strength include calcium (Ca2+) > magnesium (Mg2+) > potassium (K+) > ammonium (NH4+), and sodium (Na+).
Carbon works by using absorption and adsorption. Absorption is the process by which pollutants are trapped in the pores of the carbon. You can think of this process as a molecular-sized mechanical filter.
Decreasing hardness can be done in two main ways: dilution with softer water, or adsorption of hardening ions. Some people use reverse osmosis (RO), distilled or deionised water (DI) to dilute their tap-water to a hardness suitable for their fish.
It has a large surface area, which readily soaks up dissolved minerals and chemicals, such as fish pee, on its surface (that process is called adsorption - remember this word and its use, ...
Most mechanical filters also use chemical adsorption media, such as carbon, which aid in clarifying water so these filters are often referred to as mechanical/chemical filters.
Carbon has the ability to "catch" certain chemicals that occur in water (or air, for that matter) by "adsorption".
But some studies (see The Krib Keslar article) show that in fact 90% of the adsorption work of a piece of carbon in a good water flow in fact occurs within the first 48 hours and after 100 hours (4 days) it can be removed.
This process causes the carbon to develop huge numbers of tiny pores, which trap nonpolar wastes at the molecular levels by means of adsorption and ion exchange, and removes heavy metals and organic molecules, ...
