A chelating agent is the main component of some rust removal formulations. Citric acid is used to soften water in soaps and laundry detergents. A common synthetic chelator is EDTA. Phosphonates are also well-known chelating agents. Chelators are used in water treatment programs and specifically in steam engineering.
The most common means for removing water hardness rely on ion-exchange resin or reverse osmosis.Other approaches include precipitation methods, such as fluidized bed pellet softening, [6] and sequestration by the addition of chelating agents.
Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
Phosphonates in cooling water systems also serve to control corrosion of iron and steel. In pulp and paper manufacturing and in textile industry they serve as "peroxide bleach stabilizers", by chelating metals that could inactivate the peroxide. In detergents they are used as a combination of chelating agent, scale inhibitor, and bleach stabilizer.
It serves as a "builder", industrial jargon for a water softener. In hard water (water that contains high concentrations of Mg 2+ and Ca 2+), detergents are deactivated. Being a highly charged chelating agent, TPP 5− binds to dications tightly and prevents them from interfering with the sulfonate detergent. [3]
This white, water-soluble powder has a wide range of applications across industries. Originally derived from gluconic acid in the 19th century, Sodium Gluconate is known for its chelating properties and is utilized as a chelating agent in various processes. It finds applications in textile, metal surface treatment, cement, and more.
