Abstract

The composition and stability of complex ions of tri- and tetravalent plutonium in oxalate solutions were investigated polarographically.

The complexes Pu(C2O4)4 −4 (preponderant amount) and Pu (C2O4)4 −5 were formed in solutions of potassium oxalate with pH 3.5–6. Under these conditions, Pu+4 gave a well expressed reverse reaction wave, suitable for the quantitative polarographic determination of plutonium. The oxidation-reduction potential of this reaction in 1 M potassium oxalate was equal to 0.205 v (relative to a saturated calomel electrode at a temperature of 25 ° C). Two Pu+4 complexes were simultaneously present in solutions at pH 6–8.

From data on the solubility of Pu(C2O4)3, we determined the instability constants of the complex oxalate ions Pu(C2O4)3 −3 and Pu(C2O4)4 −5, and from the polarographic data those forPu(C2O4)4 −4 ions:

$$K_{Pu(C_2 O_4 )_4 ^{ - 3} } = 2.4 \cdot 10^{ - 12} .K_{Pu(C_2 O_4 )_3 ^{ - 3} } = 2.2 \cdot 10^{ - 11} .K_{Pu(C_2 O_4 )_4 ^{ - 4} } = 33 \cdot 10^{ - 23} $$
