Treatment of radioactive liquid waste by sorption on natural zeolite in Turkey

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

“…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, and have proven advantages with respect to immobilization and final disposal when compared with organic ion exchangers [25][26][27][28][29][30][31][32]. This study is an extension of our previous work [13], where synthetic zeolite A material was chemically prepared, completely characterized and preliminary tested as an inorganic ion exchange material for application in radioactive waste treatment.…”

The use of fixatives for response to a radiation dispersal devise attack – a review of the current (2009) state-of-the-art

“…Their unique structure consists of a negatively charged ''honeycomb-like'' framework with micropores (usually less than 1.3 nm in diameter), which enclose sufficient cations to neutralize the framework electric charge, but which are loosely bound and may be exchanged with other cations placed in contact with the zeolite. Zeolites have found applications in the treatment of industrial wastewater and in the decontamination of wastes containing radionuclides and heavy metals (Lonin and Krasnopyorova, 2007;Osmanlioglu, 2006;Ali et al, 2003).…”

Decontamination and solidification of liquid radioactive waste using natural zeolite

“…The well-known low cost materials are clay and natural zeolite. The chemistry of most ion exchange media has been extensively studied for the nuclear industry and for other waste treatment applications [3][4][5][6]. A wide range of materials is available for the ion exchange treatment of radioactive liquids [7].…”
