“…Many physical and chemical decontamination processes, such as thermal treatments, extraction, adsorption, ion exchange, and membrane separation, have been employed in the remediation of LLRWs (Rana et al 2013). Thermal treatments, such as evaporation, incineration, and vitrification, have been applied to LLRWs with a high cost of sustainable energy and the unavoidable concentration of non-evaporable materials (Choi et al 2000;Nuwan et al 2013).…”

Cs is a common radionuclide present in nuclear wastes and released from nuclear power plant accidents. It is hard to be removed from water with traditional technology. The current study aimed at developing of efficient cost-effective adsorbent for removing Cs with modified MCM-41 with specific functional groups -SH. Mesoporous material MCM-41 was selected due to its large surface area and tunable pore structure. Functional -SH groups were grafted into the pores of MCM-41 to enhance its capability of selective adsorption of Cs from multi-element (Co, Sr) water solution. The adsorption results showed that the maximum adsorption capacity was 29.24 mg/g. Both Langmuir and Freundlich models described the adsorption processes of Cs, indicating co-existence of both monolayer and multilayer adsorption in the surface and inner pores of the materials. TEM, FTIR, and Raman spectroscopy analyses indicated that -SH groups were successfully bounded into the pores of MCM-41. The present study approved the surface functional modified MCM-41 which might be a good alternative candidate for cleaning up of radionuclide Cs from nuclear power plant accidents and relevant nuclear accident events.

“…It is usually mentioned in the literature that RO/NF membranes remove at least 95% of radionuclides, in addition to improving other water quality parameters that may be a concern (Munter 2013). Rana et al (2013) wrote a review entitled 'Radioactive decontamination of water by membrane processes' and discussed the advancement in the technologies of nuclear waste treatment including membrane separation technologies for treatment of radioactive wastes. Ramanjaneyulu et al (2010) fabricated polyvinylchloride (PVC) based liquid membrane ion selective electrode (ISE) for Cs removal.…”

Application of polymeric membranes for the adsorption of hazardous pollutants may lead to the development of next-generation reusable and portable water purification appliances. Membranes for membrane adsorption (MA) have the dual function of membrane filtration and adsorption to be very effective to remove trace amounts of pollutants such as cationic heavy metals, anionic phosphates and nitrates. In this review article, recent progresses in the development of MA membranes are surveyed. In addition, recent progresses in the development of advanced adsorbents such as nanoparticles are summarized, since they are potentially useful as fillers in the host membrane to enhance its performance. The future directions of R&D in this field are also shown in the conclusion section.

“…Among various membrane-separation processes that are used for the radioactive decontamination of water, pressure driven processes, including reverse osmosis (RO) have already proven themselves as the most versatile methods [4]. RO technology has been employed successfully in several nuclear facilities, such as Chalk River Laboratories in Canada [5], Nine Mile Point station (NMP), Comanche Peak NPP and Dresden NPP in the United States [6,7], as summarized in Table 1.…”
