Radiation-assisted synthesis of Prussian blue nanoparticles using sugar as stabilizer

Prussian blue (PB) nanoparticles were successfully synthesized via a γ radiation route in aqueous solutions using sugar as stabilizer at room temperature and ambient pressure. The particle size and shape can be affected by stabilizer and radiation conditions. When the stabilizer was sucrose and the radiation dose was 30 kGy, well-dispersed and uniform PB nanoparticles were obtained, which are 100–200 nm in diameter. They exhibit good ions exchange properties and have maximal Cs + adsorption capacity of 125.8 mg g −1 , which may be applied in radioactive wastewater treatments, ion battery etc.
