Evaluation of zeolite A for the sorptive removal of Cs+ and Sr2+ ions from aqueous solutions using batch and fixed bed column operations

Preliminary study on removing Cs+/Sr2+ by activated porous calcium silicate—A by-product from high-alumina fly ash recycling industry

“…Evaporation can reduce the volume of radioactive wastewater efficiently. But this method has many disadvantages, such as high energy consumption, difficulty in operation, and easily causing secondary pollution (El-Kamash, 2008). Comparing with other methods, adsorption or ion-exchange technology becomes one of the most commonly used methods due to its simplicity, selectivity, and efficiency (Danilin and Drozhzhin, 2007).…”

Studies Regarding the Influence of the Ultrasonication Conditions on the Adsorption Performance of Obtained Ionic Liquid Impregnated Materials

“…3. In the IR spectra of these compounds are found of the absorbtion bands from [BmimPF 6 ] vibrational spectrum (the bands between 2970-2850cm -1 are stretching vibration of CH 3 and CH 2 ; the imidazolium CH stretching: 3125cm -1 , 3177cm -1 ; the bands around 830cm -1 and 740cm -1 are attributed to the antisymmetric respectively symmetric stretching vibrations PF 6 anion) [29]. The infrared spectra show that the highest quantity of [BmimPF 6 ] was impregnated onto Florisil when 100% amplitude was used (Fig.…”

Liquid Radioactive Wastes Treatment: A Review

“…The cationic radioisotopes, present in the liquid effluents of low and intermediate level liquid wastes, can be removed by the ion exchange with the Na + ions of the zeolites. These inorganic materials possess high exchange capacity, possible selectivity and specificity, good resistant to radiation [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Recently, Zeolite A was synthesized and evaluated, as inorganic ion exchange material, for the removal of Cs and Sr ions from aqueous solutions in both batch and fixed bed column operations [24].…”
