Prussian blue nanoparticles–mediated sensing and removal of 137Cs

Prussian blue nanoparticles (PBNPs) with controlled nano-geometry were synthesized from a single precursor (potassium hexacyanoferrate) in the presence of three different reagents, namely, polyethylenimine (PEI), tetrahydrofuran (THF)/H 2 O , and 2-(3,4-epoxycyclohexyl)-ethyl-trimethoxysilane (EETMS)/cyclohexanone, which enabled nucleation stabilization PBNPs variable plasmonic activities for selective sensing removal cesium radionuclides. The results this study show ions based on nano-geometry, magnetic behavior, fluorescence quenching ability as function ion concentration first time. A similar process was used to synthetically incorporate mesoporous silica potential use adsorption 137 Cs, followed by detection radioactivity. distribution coefficient (Kd) nuclide Cs calculated be 3.2 × 10 4 mL/g −1 displaying both Langmuir Freundlich isotherms. activity has fluorometric ions; regulating spatial control between functional probe molecules is promising approach PBNP-enhanced resonance energy transfer–based sensing. Similarly, display superparamagnetic behavior; these properties observed linearly dependent concentration.
