Although minor in abundance in Earth's crust (U, 2–4 ppm; Th, 10–15 ppm) and in seawater
(U, 0.003 ppm; Th, 0.0007 ppm), light actinides (Th, Pa, U, Np, Pu, Am, and Cm) are …

Reactions of the light actinide ions (Th to Cm) at the mineral− aqueous solution interface
have attracted much attention during recent years. Initially research was mainly driven by the …

A majority of clay minerals contain Fe, and the redox cycling of Fe (III)/Fe (II) in clay minerals
has been extensively studied as it may fuel the biogeochemical cycles of nutrients and …

Understanding sorption and desorption processes is essential to predicting the mobility of
radionuclides in the environment. We investigate adsorption/desorption of cesium in both …

Anthropogenic radionuclides, including long-lived heavy actinides such as americium and
curium, represent the primary long-term challenge for management of nuclear waste. The …

Abstract Uranyl (UO 2 2+) species with hexavalent U (VI) oxidation state is the most
ubiquitous form of uranium in natural minerals, underground water, contaminated soils, and …

The long-term safe disposal of radioactive waste corresponds to a challenging responsibility
of present societies. Within deep geological waste disposal concepts, host rocks correspond …

In this study, Np (V) retention on Illite du Puy (IdP) was investigated since it is essential for
understanding the migration behavior of Np in argillaceous environments. The presence of …

Abstract Tetravalent actinides, An (IV), are usually assumed to be little mobile in near-neutral
environmental waters because of their low solubility. However, there are certain …

Plutonium (Pu) adsorption to and desorption from mineral phases plays a key role in
controlling the environmental mobility of Pu. Here we assess whether the adsorption …
