In this study, biogenic Mn(IV) oxide was applied to remove Ra from mine water collected from a U mill tailings pond in the Ningyo-toge center. Just 7.6 mg of biogenic Mn(IV) oxide removed more than 98% of the $$^{226}$$Ra from 3 L of mine water, corresponding to a distribution coefficient of 10$$^{7.4}$$ mL/g for Ra at pH 7. The obtained value was convincingly high for practical application of biogenic Mn(IV) oxide in water treatment.

Improved immobilization of Re(VII) from aqueous solutions $$via$$ bimetallic Ni/Fe$$^{0}$$ nanoparticles; Implications towards Tc(VII) removal

Maamoun, I.; Tokunaga, Kohei; Dohi, Terumi; Kanno, Futoshi*; Falyouna, O.*; Eljamal, O.*; Tanaka, Kazuya

Frontiers in Nuclear Engineering (Internet), 2, p.1142823_1 - 1142823_17, 2023/03

https://doi.org/10.3389/fnuen.2023.1142823

Recently, the rapid development of nuclear power technologies and the continuous energy demand around the world exhibited massive amounts of contaminated water with radionuclides. Technetium-99 ($$^{99}$$Tc) is one of the long-lived radionuclides with a highly mobile anionic form (Tc(VII)) in aqueous solutions. Hence, the rapid and efficient Tc(VII) removal from radioactive water has emerged as a challenging issue. In this work, bimetallic nickel/iron nanoparticles (Ni/Fe$$^{0}$$) were prepared to enhance the immobilization of rhenium (Re(VII)) from aqueous solutions, as the surrogate of Tc(VII).

We collected surface sediment and water samples at a U mill tailings pond in the Ningyo-toge center. Radioactivity concentrations of $$^{226}$$Ra in sediments were 12,000 - 29,000 Bq/kg while those in water ranged from 60 to 580 mBq/L. As a result, apparent distribution coefficients of Ra between ferric sediment and water were estimated to be 3.1 $$times$$ 10$$^{4}$$ - 3.8 $$times$$ 10$$^{5}$$ mL/g, which were higher than reported ones for ferrihydrite and goethite. This suggests that another host on which Ra is strongly fixed would be present in sediment if we assume equilibrium between sediment and water. It is possible that Mn(IV) oxide as a minor component contributed to an increase in the apparent distribution coefficients. Another possibility is upward flow of pore water containing $$^{226}$$Ra or diffusion of $$^{226}$$Ra released from lower sediment layers. Either scenario provides additional input of $$^{226}$$Ra to surface sediment. In this case, surface sediment and water did not reach equilibrium with each other, but $$^{226}$$Ra concentrations in surface sediments were governed by dynamics through input of $$^{226}$$Ra from porewater as well as groundwater in sediment-water interaction.
