As the sodium salt, used as a water softener, to stabilize drugs rapidly decomposed in the presence of traces of metal ions, and as an anticoagulant; as the sodium calcium salt, used to remove radium, lead, strontium, plutonium, and cadmium from the hard tissue, forming stable un-ionized soluble compounds that are excreted by the kidneys.
