“…which are often present in contaminated effluents [1,4,5,[16][17][18]. Since metal HCF has a well-known perovskite-like face-centered cubic crystal structure, with a channel diameter of around 3.2 Å, small hydrated cations such as Cs + can be inserted, whereas the larger hydrated ions such as Na + are selectively rejected [4,19].…”

“…In order to address such issues, numerous studies have considered the immobilization of the small sized metal HCF particles, either by grafting onto porous media [5,16,20,22], or encapsulating in a polymer matrix [1,3,23,24]. Turgis et al…”

“…To meet our energy needs in the 21st century, nuclear power has emerged as one of the most promising alternatives to fossil fuels, providing approximately 9.7 % of the world's energy [1]. However, from an environmental perspective, nuclear energy can pose a threat due to the release of approximately 2000-2300 metric tons of radioactive waste into the environment each year [1].…”

“…However, from an environmental perspective, nuclear energy can pose a threat due to the release of approximately 2000-2300 metric tons of radioactive waste into the environment each year [1]. Thus, for the continuous and long-term operation of nuclear facilities, environmental remediation and confinement of generated wastes remain a key priority [2].…”

Poly(vinyl alcohol) hydrogel. 2The KCuHCF embedded PVA-Citric acid hydrogel adsorbent was synthesized through a facile twostep method for the selective and rapid Cs + removal. 3 Highlights The HPC was synthesized by a noble solvent-assisted method. The HPC showed superior Cs + removal capacity of 667 mg/g KCuHCF. The HPC retained remarkable Cs + removal efficiency of 99.5 % in 30 min. In a wide pH range from 2 to 10, the HPC displayed stable Cs + removal effi ciency. Moreover, the adsorbent revealed stable and high Cs + removal efficiency of 99.9 % across a wide pH range from 2 to 10. The kinetics of Cs + removal was remarkably rapid with 99.5% removal achieved within 30 min from a dilute Cs + solution (9.18 ppm). When using seawater, the HPC exhibited almost unaltered Cs + removal efficiency above 99.5 %, and high distribution coefficient K d value of 7.7 10 5 mL/g at an extremely low Cs + concentration (0.67 ppm, V/m = 1000 ml/g), whichhighlighted the tremendous affinity for Cs + .5

RESUMO -O grafeno, uma das formas alotrópicas do carbono, tem sido considerado o futuro da tecnologia em todo o mundo. A preparação de materiais derivados de grafeno tem merecido destaque nos últimos anos, tendo em vista as excelentes propriedades mecânicas, térmicas e elétricas desses materiais. Este projeto utiliza um filme de óxido de grafeno na preparação de filmes nanocompósitos contendo hexacionaferrato de ferro (III), conhecido como azul da Prússia. Através do presente projeto pretende-se desenvolver uma rota inovadora de preparação desse tipo de nanocompósito, através do método interfacial, com modulação das propriedades através do controle de morfologia, tamanho e dispersão do azul da Prússia sobre as folhas de óxido de grafeno. Os filmes obtidos foram caracterizados através das técnicas de espectroscopia por energia dispersiva de raios X (EDS ou EDX), técnicas de microscopia eletrônica de varredura e espectroscopia Raman. Essas técnicas mostraram a eficiência do método interfacial para obtenção dos filmes e revelaram características importantes para os diferentes materiais preparados, objetivando sua aplicação como sensor para diferentes analitos, além de componente ativo em dispositivos ópticos.
