An overview of recent studies in which the transport of radionuclides in porous materials has
been recently modeled is provided. The focus is on the modeling based on balance …

Due to the development and utilization of nuclear energy, the safe disposal of nuclear waste
needs to be urgently addressed. In recent years, the utilization of microorganisms' …

Abstract Fe 3 O 4 and Fe 3 O 4/bentonite were prepared by chemical co-precipitation
method. They were characterized by X-ray powder diffraction (XRD), Fourier infrared …

Highly efficient and irreversible capture of radioactive barium from aqueous media remains
a serious task for nuclear waste disposal and environmental protection. To address this task …

The history of sorption and ion-exchange processes starts with the use of natural materials
which properties were discovered coincidentally and ends with the age of polymer and …

Abstract 129 I and 79 Se are potentially important anionic radionuclides in safety
assessments due to their high mobility, radiotoxicity, and long half life's (1.7× 10 7 and 3.27× …

Abstract 79 Se and 129 I are potentially important anionic radionuclides in safety
assessments due to its radiotoxicity, high mobility and long half life's (3.27× 10 5 and 1.7× 10 …

Clays and specially bentonite are widely used as natural adsorbents for wastewater
treatment and as a barrier in landfills to prevent the contamination of subsoil and …

ABSTRACT The removal of Pb2+, Ni2+, Cd2+, Zn2+, Cu2+, and UO22+ ions from wet
phosphoric acid were employed to gain the purified acid by the low-cost adsorbent that …

The radioactive wastes from different activities have to be safely disposed of and isolated
from the human environment. The retardation of radioactive materials by designed barriers …
