Summary: This paper presents a simple and cost-effective method for producing a 3D porous and redox-active Prussian blue-graphene hydrogel. The hydrogel, obtained through the reduction of graphene oxide sheets by ferrous ions, exhibited high selectivity for cesium ions. The hydrogel's adsorption potential for cesium ions was significantly improved compared to previous studies, fitting well with the Langmuir isotherm and the pseudo-second order kinetic model.

Summary: In this study, magnetic Prussian blue nanospheres (MPBNs) were developed as an effective adsorbent for the removal of cesium ions from wastewater. The MPBNs showed spherical shape with rough surface, and their adsorption process followed Freundlich isotherm and quasi-second-order kinetics. The adsorption capacity of MPBNs was controlled by the diffusion step in particles. Moreover, MPBNs could be easily separated from water by a magnetic field, making them suitable for engineering applications in cesium-containing wastewater.

Summary: This study successfully synthesized Prussian blue functionalized layered double hydroxide (PB-LDH) to remove both Cs+ and IO3- from mixed waste solutions. The removal mechanism of Cs+ involved redox coupled alkali metal ion transport, while IO3- was mainly removed through ion exchange with intercalated Cl- and the redox effect of Co ions.

Summary: In this study, alginate/hydroxyapatite/graphene oxide (AHGO) nanocomposite hydrogel beads (nhb) were synthesized and studied as an efficient and environment-friendly adsorbent for cationic dyes. The results showed that AHGO-nhb had a high adsorption capacity for methylene blue (MB). The adsorption process was found to be spontaneous and exothermic, primarily involving electrostatic interaction, n-pi interaction, and pi-pi interaction on the surface of the adsorbent.
