In recent decades, interest in plutonium mobility has increased significantly due to the need
of the United States, as well as other nations, to deal with commercial spent nuclear fuel …

Plutonium is one of the most toxic components of spent nuclear fuel and of nuclear wastes,
which is characterized by very complex chemical behaviour both in engineering processes …

The nanoscience field often produces results more mystifying than any other discipline. It
has been argued that changes in the plutonium dioxide (PuO2) particle size from bulk to …

This chapter discusses key aspects related to the assessment of the environmental impact of
plutonium, such as sources, speciation, and underlying processes important for ecosystem …

The aim of this study is to synthesize PuO2 nanoparticles (NPs) at low pH values and
characterize the materials using laboratory and synchrotron-based methods. Properties of …

Pu (IV) and Pu (V) sorption to goethite was investigated over a concentration range of 10–15–
10–5 M at pH 8. Experiments with initial Pu concentrations of 10–15–10–8 M produced …

Abstract Neptunium (Np (V)) sorption onto a purified illite is investigated as a function of pH
(3–10) and [Np VO 2+] tot (3× 10− 8–3× 10− 4 M) in 0.1 M NaCl under Ar atmosphere. After …

Pu (V) adsorbed to the surface of montmorillonite clay can be reduced to Pu (IV). In this
work, the role of clay structural Fe on this surface mediated reduction reaction was …

The geochemical behavior of Pu strongly depends on its redox speciation. In this study, we
investigated Pu sorption onto Na–illite, a relevant component of potential host rocks for high …

We explored the speciation and kinetics of the Pu (VI)-citrate and Pu (III)-citrate systems
(pHm= 2.5–11.0, I= 0.1 M NaCl, T= 23° C, O2 (g)< 2 ppm) using ultraviolet–visible–near …
