Chelating agents, DTPA

scroll

Chemicals such as diethylenetriamine pentaacetate are chelators. Chelators are organic compounds capable of integrating metal ions in the organic molecule in such a way that the metal ion loses its chemical properties essential for its biological behaviour and can therefore be excreted more rapidly from the body. Thus, effective decorporation agents in the form of Ca-DTPA and Zn-DTPA - in particular for plutonium - are available.
