dc.description.abstract |
The paper presents the researches on the synthesis, characterization and decontamination capacities tests of the nanostructured zero-valent iron, which can be used for the radioactive contaminated water treatment from the uranium ore processing plant.There were synthesized two types of nanostructured iron namely: nanostructured zero-valent iron obtained by the boron hydride reducing method and nanostructured iron laid-down on the solid support - activated carbon Purolite resin type AG 20G and Purolite resin type C 160. The research for testing the decontamination capacity of the synthesized materials, which were added commercial resin Purolite ARSEN-Xnp impregnated with iron nanoparticles, have led to a decontamination capacity varied directly as the amount of nanostructured iron from the reactive material. Distribution coefficient values (for uranium) obtained after experiments are related both to the content of nano-iron material reagent and their adsorption properties. Utilization of these types of materials leads to a process with a decontamination efficiency of over 99.99% according to the environmental quality standards in the field of water policy. |
