“…Nuclear energy is widely considered as a clean and efficient energy source (Matsui et al 2008;Menyah and Wolde-Rufael 2010;Corner et al 2011), but the rapid development of nuclear energy brings some problems. Radioactive waste (including three forms solid, liquid, and gas) is one of the problems (Choudri and Baawain 2015;Ikeda et al 2007), especially the radioactive wastewater due to it poses a serious threat to public health and ecological environment.…”

How to remove radionuclides from the radioactive wastewater quickly and efficiently is of great significance for mitigating the adverse effects of nuclear accident. Our previous researches have shown that metallic radionuclides (Cs + , Sr 2+ , and Ba 2+ ) can be chemisorbed on monolayer 2H-MoS 2 . To enhance the adsorption capacity of the monolayer 2H-MoS 2 to the metallic radionuclides, the effects of phase, strain, pressure, vacancy, and doping on the adsorption of the metallic radionuclides on the monolayer 2H-MoS 2 were investigated by using the first principles calculation method in this paper. The calculation results show that the adsorption energy of the metallic radionuclides on the monolayer 2H-MoS 2 is decreased by phase, strain, vacancy, and doping, while the pressure has little effect on the adsorption energy. The adsorption energy change indicates that the adsorption of the metallic radionuclides on the monolayer 2H-MoS 2 is enhanced by phase, strain, vacancy, and doping. The adsorption energy change is mainly contributed by the electron structure change, which caused by phase, strain, vacancy, and doping. Especially, the change of charge transfer between the metallic radionuclides and their nearest atoms on the monolayer 2H-MoS 2 is a very critical factor.
