Decontamination of very dilute Cs in seawater by a coagulation-precipitation method using a nanoparticle slurry of copper hexacyanoferrate
We examined the highly selective Cs adsorption ability of a potassium copper hexacyanoferrate (KCuHCF) slurry ink in seawater, i.e. very low Cs concentration in the presence of Na + , K + , Mg 2+ , Ca 2+ , and Cl − ions at high concentrations. The rational synthesis of the KCuHCF nanoparticle (KCuHC...
