Electrochemical and complexation properties of neptunium (Np) are investigated in aqueous perchlorate and nitrate solutions by means of cyclic voltammetry, bulk electrolysis, UV …
X-ray absorption spectroscopy has been used to study the reduction of adsorbed U (VI) during the Fe (II)-accelerated transformation of ferrihydrite to goethite. The fate of U (VI) was …
U (VI) doped hematite was synthesized and exposed to two different organic reductants with E 0 of 0.23 and 0.70 V. A combination of HAADF-TEM and EXAFS provided evidence that …
