Diethylenetriaminepentacetic

Fig. 6.8. Structures of some common fluorophores. DPH = diphenylhexatriene NBD = nitrobenzoxadiazole Tb-DTPA-csl24 = terbium diethylenetriaminepentacetate-carbostyril 124, DAPI = 4, 6-diamidino-2-phenylindole Nile red = 9-(diethylamino)-5H-benzo-[a]phenoxazin-5-one.

In the presence of complexing agents at a sufficiently high concentration it is possible to prevent the formation of the Pu(IV) polymer. Acetate at a concentration of 5 x 10 2m facilitated the retention of 90% of Pu(IV) as themonomerin concentrations of 10 sm Pu(IV) when the pH was raised from pH 2.8 to pH 5.7. However, citric acid and diethylenetriaminepentacetic acid (DTPA), both at 5 x 10 4m, were even more efficient at preventing polymer formation (14).

Contamination by plutonium of atomic-energy workers can be effectively overcome by daily injections of diethylenetriaminepentacetic acid (Smith, Chapman, and Marlow, 1969). More powerful, related substances are now on trial.
