Acknowledgement Part of the work on radionuclide sorption was supported by the Russian Science Foundation (project 14-13-01279). We also acknowledge the Russian Foundation for Basic Research (project 12-05-00208) for supporting Raman and IR measurements. The authors thank the M.V. Lomonosov Moscow State University Program of Development for partial support of HRTEM measurements. We are also grateful to the “Nanochemistry and nanomaterials” user facility of the Department of Chemistry of MSU for providing the XPS measurements.

Reich Institue of Nuclear Chemistry, Johannes Gutenberg-Universität, 55099 Mainz, Germany (Received May 15, 2010; accepted in final form February 16, 2011) Sorption / Neptunium / Kaolinite / Clay Summary. The sorption behavior of neptunium(V) onto the clay mineral kaolinite was studied in batch experiments under different experimental condi- tions: [Np(V)] = 7×10−12–8×10−6 M, solid

Radiochim. Acta 97, 99–103 (2009) / DOI 10.1524/ract.2009.1579 © by Oldenbourg Wissenschaftsverlag, München Neptunium(V) sorption onto gibbsite By T. Wu∗, S. Amayri and T. Reich∗ Institue of Nuclear Chemistry, Johannes Gutenberg-Universität, 55099 Mainz, Germany (Received July 23, 2008; accepted in revised form August 15, 2008) Sorption / Neptunium / Gibbsite Summary. The sorption behavior of neptunium(V) on gibb- site (γ -Al(OH)3) was studied by batch experiments in the presence/absence of ambient CO2 as a function of solid-to- liquid ratio, pH, ionic strength

Acta 2014; 102(6): 489–504 Tashi Parsons-Moss, Harun Tüysüz, Deborah Wang, Stephen Jones, Daniel Olive, and Heino Nitsche* Plutonium sorption to nanocast mesoporous carbon Abstract: Nanocast ordered mesoporous carbons are at- tractive as sorbents because of their extremely high sur- face areas and large pore volumes. This paper compares Pu uptake, added as Pu(VI), to both untreated and chemi- cally oxidized CMK-(carbon molecular sieves from KAIST) type mesoporous carbon with that to a commercial amor- phous activated carbon
