Chemical weathering process that involves the extraction or metallic cations from rocks and minerals by chelates.

An equilibrium reaction between a metal ion and a complexing agent. Chelation reactions are characterized by the formation of more than one bond between the metal and a molecule of the complexing agen [..]

Binding of a metal ion by a large molecule to form a soluble complex; chelation therapy uses large molecules such as EDTA (ethylene diamine tetraacetic acid) to remove excess metals (like lead or iron) from tissues and enable their excretion.

A process by which certain micronutrients are treated to keep them readily available to a plant once they are introduced into the soil.

chemical weathering in which chelates draw metallic cations (positively charged ions) out of rocks and rocky minerals. Ultimately, all forms of weathering have a hand in forming soils. Also: a controversial medical procedure in which the organic chemical EDTA is injected into the body to chelate heavy metals from the blood. The list of claimed bene [..]

a form of chemical weathering. Organic acids released during decomposition release iron and aluminium from the A horizon and combine with them to form chelates.

chemical combination with heavy metal (pop)

(n) (medicine) the process of removing a heavy metal from the bloodstream by means of a chelate as in treating lead or mercury poisoning(n) the process of forming a ring by forming one or more hydroge [..]

The formation or presence of bonds (or other attractive interactions) between two or more separate binding sites within the same ligand and a single central atom. A molecular entity in which there is chelation (and the corresponding chemical species) is called a "chelate". The terms bidentate (or didentate), tridentate, tetradentate... mu [..]

A process in which a metal ion is coordinatively bound to an organic molecule forming a heterocyclic ring.

A chemical complexing (forming or joining together) of metallic cations (such as copper) with certain organic compounds, such as EDTA (ethylene diamine tetracetic acid). Chelation is used to prevent t [..]

A process that wraps or binds the minerals in amino acids, it uses an agent, such as the chemical compound EDTA, to remove heavy metals from the body.

A chemical complexing (forming or joining together) of metallic cations (such as copper) with certain organic compounds, such as EDTA (ethylene diamine tetracetic acid). Chelation is used to prevent t [..]
