These ligands, which are often organic compounds, are called chelants, chelators, chelating agents, or sequestering agent. The ligand forms a chelate complex with the substrate. The term is reserved for complexes in which the metal ion is bound to two or more atoms of the chelating agent. COMPLEX: The term complex in chemistry, also called a File Size: 1MB.

Carbon sequestration, the long-term storage of carbon in plants, soils, geologic formations, and the ocean. In response to concerns about climate change resulting from increased carbon dioxide concentrations in the atmosphere, interest has been drawn to geoengineering techniques such as carbon capture and storage. The effectiveness of three different phosphate based sequestering agents was determined at three dosages (%, %, and % stoichiometric). Source waters had a pH between 7 and 8 as well as varying concentrations of iron, manganese, alkalinity, calcium, magnesium, and total organic carbon.
When held inside the complex, the ions have a limited ability to react with other ions, clays or polymers. Ethylenediamine tetraacetic acid (EDTA) is a well-known sequestering agent for the hardness ions, such as Ca +2, and is the reagent solution used in the hardness test protocol published by API. Polyphosphates can also sequester hardness ions. Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents.

The role of soil the ecosystem is increasingly being recognized with the realization that it has the capacity of reducing the concentration of carbon dioxide (CO 2) in the atmosphere (through sequestration of organic carbon in the soil) and also by releasing this CO 2 back into the atmosphere (through mineralization of soil organic matter).

A complementary approach to removing excess reagents from a reaction solution using a support-bound sequestering agent is to immobilize the reagent on an appropriate solid phase.

The term sequestering agent is generally applied to chelating agents who form water-soluble. Food additive, any of various chemical substances added to foods to produce specific desirable ves such as salt, spices, and sulfites have been used since ancient times to preserve foods and make them more the increased processing of foods in the 20th century, there came a need for both the greater use of and new types of food additives.
