Removal Of Radiocobalt From Edta-Complexes Using Titanium Antimonate Sorbents
نویسندگان
چکیده
Two titanium antimonate materials were tested for the removal of radiocobalt from a solution containing complexing agent EDTA to simulate a nuclear power plant decontamination solution. The first material had a mixture of pyrochlore and rutile structures and it showed high removal (91 %) of radiocobalt was removed in the presence of EDTA. The second material, which had a mopungite structure, showed even higher (97 %) removal of radiocobalt. In addition, both materials had a very high radiocobalt uptake (> 99 %) in acidic solution when EDTA was absent. Results indicate that the titanium antimonate (TiSb) materials are highly promising for radiocobalt removal from nuclear decontamination solutions.

This work aims to investigate the competitive time-dependent desorption rate of heavy metals (lead, zinc, nickel) coexisting with phenanthrene from natural high buffering soil. Two non-ionic surfactants (Tween 80 and Brij 35) combined with disodium ethylene diamine tetraacetate salt (Na2-EDTA) were utilized as the reagents. The contaminants’ time-dependent desorption data was fitted with five k...
متن کاملSurvey of Nitrate Removal Method from Aqueous Solutions Using Titanium Dioxide Nano-Photocatalyst
Background & objectives: Because of its very high solubility, nitrate penetrates easily into soil and underground waters. Surface waters such as lakes, reservoirs, and rivers are exposed to nitrate pollution. Photocatalytic processes have a high potential for nitrate removal due to complete oxidation, lack of formation of multi-cycle metabolites and the availability of catalysts. The purpose of...
