Most water contains metal ions which can cause detrimental effects to chemical processes in the home and in industry. Metal ions in the environment are often controlled or removed by the use of chelating agents so as to prevent these effects. However, commonly used chelating agents are poorly biodegradable and concerns have been raised about their environmental effects. Considerable effort has gone into designing greener, more biodegradable alternatives, but as the reactivity of the alternatives is not the same as that of the original chelating agents, chemists have had to use their skill to find new, greener designs that are as effective without harming the environment.
