| 21. | It functions as a siderophore, a small chelating agent with a high affinity for iron.
|
| 22. | Other substances called chelating agents keep the water clear.
|
| 23. | It also dissolves well in solutions of the chelating agents such as EDTA and oxalic acid.
|
| 24. | When metal ions are present in high concentrations, use of a chelating agent may be necessary.
|
| 25. | Therefore, ACE can be inhibited by metal-chelating agents.
|
| 26. | In detergents they are used as a combination of chelating agent, scale inhibitor, and bleach stabilizer.
|
| 27. | EDTA is a metal chelating agent and is commonly used in foods to prevent oxidative rancidity.
|
| 28. | Other processes include precipitation and complexation of surfactants, or chelating agents that bind to radioactive elements.
|
| 29. | Water containing these chelating agents can leach metal from water treatment equipment as well as pipes.
|
| 30. | However, an alternate hypothesis as to how they work is that they act as chelating agents.
