Results are presented from the ongoing international study, namely Chernobyl Pilot Site Project, aimed at characterization and modeling of process controlling Sr releases from the shallow trench at Chernobyl NPP site containing nuclear fuel particles and subsequent radionuclide transport in the underlying eolian and alluvial sand aquifer. Microscopic analyses of fuel particles separated from wa...

Removal of uranium [U(VI)] from aqueous solutions with humic acid-immobilized zirconium-pillared clay (HA-Zr-PILC) was investigated using a batch adsorption technique. The adsorbent was characterized using XRD, FTIR, SEM, TG/DTG, surface area analyzer and potentiometric titration. The effects of pH, contact time, initial concentration, adsorbent dose, and adsorption isotherm on the removal proc...
