“…A. Belgacem et al found lower sorption capacities for uranium using activated carbon in comparison to our results [50]. Finally comparable data presented in the literature concerning the removal of Ba and Eu by ash and zeolites whereas slight higher values observed by P. Sharma et al in the case of Eu-sorption on nanocrystalline zeolite [35][36][37]51].…”

“…The investigation of the uranium sorption behavior of the sorbents has already been completed and published [38], whereas the study of the other cations is in progress. However, the new materials synthesized from fly ash under moderate experimental conditions exhibited satisfactory uptake values for Cr, Cd, U, Cs, Ba and Eu compared to that of other zeolitic materials based on ash referred in the literature [35][36][37][44][45][46][47][48][49][50][51]. This is a demonstration that can be successfully applied as low-cost sorbents in the environmental technology.…”

Power plant ash was used to synthesize new materials by hydrothermal treatment and ultrasonic activation in an alkaline medium (5 M NaOH) under moderate experimental conditions. The obtained materials were characterized by a variety of techniques (SEM/EDS, INAA, XRD, FTIR, BET). Preliminary investigation of the Ba, Cd, Cr, Cs, Eu and U removal efficiency was performed by batch experiments using radiotracers and spectroscopic techniques as well as desorption studies. The results indicated that the new materials are very efficient in removing the above mentioned metals from aqueous solutions and can be considered as potential low-cost sorbents in environmental technology.

The effectiveness of a low cost sorbent produced by thermal modification of ammonium heptamolybdate (AHM) in adsorption of radionuclides and heavy metals was investigated. The product was characterized by XRD, SEM and Raman spectroscopy. Sorption experiments were performed in Pb, U, Cs, Ba and Eu solutions (pH 2.0-6.0). The obtained isotherms were simulated by Langmuir and Freundlich isotherms and kinetics data were used in order to evaluate the sorption mechanism. The results showed the high and selective efficiency of the AHM-derived MoO 3 especially in Pb and U removal whereas the desorption experiments revealed its environmental applicability under real conditions for the investigated metal cations.

It is of vital importance to capture lanthanides (nuclear fission products) from waste solutions for radionuclide remediation owingt ot heir hazards.T he effective separation of lanthanides are achieved by an acid/base-stable and radiation-resistant vanadate,n amely,[ Me 2 NH 2 ]V 3 O 7 (1). It exhibits high adsorption capacities for lanthanides (q m Eu = 161.4 mg g À1 ;q m Sm = 139.2 mg g À1 ). And high adsorption capacities are maintained over ap Hr ange of 2.0-6.9 (q m Eu = 75.1 mg g À1 at low pH of 2.5). It displays high selectivity for Eu 3+ (simulant of An 3+ )a gainst al arge excess of interfering ions.Itcan efficiently separate Eu 3+ and Cs + (or Sr 2+ )with the highest separation factor SF Eu/Cs of 156 (SF Eu/Sr of 134) to date. The adsorption mechanism is revealed by calculations and XPS,E XAFS,R aman, and elemental analyses.T hese merits combined with facile synthesis and convenient elution makes the title vanadate ap romising lanthanide scavenger for environmental remediation.
