Chelation - Wikipedia, the free encyclopedia |
 | | Chelation (from Greek χηλή, chelè, meaning claw) is the process of reversible binding (complexation) of a ligand; the chelant, chelator, chelating agent, sequestering agent, or complexing agent; to a metal ion, forming a metal complex, the chelate. |
 | | In ecology chelation compounds are related to the mobilization of metals in the soil, the uptake and the accumulation of metals into plants and micro-organisms and as a mechanism for resistance and hyperaccumulation adaptations. |
 | | Chelators are used in chemical analysis, as water softeners, as preservatives, and in medicine (chelation therapy), where they are employed to safely bind with poisonous metal agents such as mercury, arsenic, or lead to stabilize them and allow them to be excreted without further interaction with the body. |
