The stability of Pu(IV) polymer suspensions, the solubility of the polymer, and the nature of the soluble plutonium species were studied from pH 3 to 7 in dilute chloride and in dilute nitrate solutions. Polymer suspensions are not stable at pH values above 5, and hence the polymer is not expected to be mobile in the lithosphere. The solubility of polymer is intermediate between the solubilities of Pu(OH)4(a) and PuO2(c) and it is <10 ppb in air-equilibrated dilute salt solutions at pH 7. The soluble plutonium is present as plutonyl species.
