“…The NFA-Y had an approximate adsorption capacity of 167.12 mgg -1 . [127] It has been found that aluminosilicate with a CHA-type zeolite structure totally eliminates Sr 2+ ions at very high levels. [128] Synthetic zeolite worked well to eliminate 137 Cs and 90 Sr ions from waste water.…”

The presence of various types of contaminants such as heavy metals, emerging organic contaminants, pesticides, organic waste, organic dyes, radionuclide's, fluorides, etc. cause water pollution. These pollutants are of concern to engineers, environmentalists and scientists. Due to the lack of freshwater, it is very important to recycle the wastewater after treatment to remove organic contaminates and heavy metal pollutants. Chemical precipitation, ion exchange, adsorption, filtration via membranes, flocculation, coagulation, flotation, and electrochemical techniques are just a few of the methods used to eliminate contaminants from wastewater. The most popular and effective among these is the ion exchange process. New generation hybrid materials, inorganic three‐dimensional matrices and synthetic organic resins are some examples of the different types of ion exchange resins. Most investigations have found that pseudo‐first and second order kinetic studies are important in the contaminant removal process. The isotherm model, which also incorporates the Langmuir, Freundlich, Dubinin Radushkevich, and Temkin equations, proved appropriate for most of the research. For an example, orgnic polymeric materials can maximum uptake capacity of 4.28 mmolg‐1 Cr(VI) and 1.97 mmolg‐1 As(V) respectively. The effectiveness of ion exchanger and its current trends in various environmental applications have been the main topics of this review article.

“…34,35 The adsorption/ion-exchange capacity of zeolites depends on the structure type, the pore diameter, and the Si/Al ratio of zeolites. 36 To date, zeolites with framework type codes of LTA , 37 GIS , 38 CHA , 39 MOR , 40 FAU , 41 MFI , 42 and *BEA 42 have been investigated to remove radionuclides. Since the concentration of 137 Cs in radioactive wastewater is usually very/extremely low, the selectivity of the adsorbent is particularly important.…”
