Abstract:
The hydration of transition metals, lanthanides (Ln) and actinides (An) in aqueous solution is a topic that attracts the attention of many scientists as this process is of relevance to environmental problems and medicinal applications. Actinides have an environmental and toxicological interest since they are nuclear fuel wastes with both chemical and radiochemical toxicity, becoming extremely difficult to handle it from experimental point of view. In this context, a more quantitative use of the Ln/An analogy is desirable to develop theoretical approaches capable of reproduce the experimental data existing for the former and capable of predict macroscopic properties in the solvation of the latter.
In order to investigate hydration of lanthanide/actinide and halides counter ions[1], one of our goal is to develop a polarizable force-field model adjusted on state-of-the art ab initio calculations[1, 2, 3]. Another goal is to discuss the accuracy of the model by investigating the impact of the parametrization uncertainties in the bulk water model and in the metal-water interaction model on the molecular simulation results.
