We report on the synthesis of cesium ion-imprinted polymer nanoparticles that were prepared by a precipitation polymerization strategy using dibenzo-24-crown-8 ether as a selective crown ether, methacrylic acid as the functional monomer, ethyleneglycol dimethacrylate as the crosslinker, and AIBN as the radical initiator. The prepared sorbents have a diameter of 50-90 nm and display highly selective binding capability for Cs(I) ion, with rapid adsorption and desorption. The maximum adsorption capacity is 50 mg g-1, and the preconcentration factor is around 100 at pH 9. 0. Cesium ion was then determined by flame photometry with a detection limit (3σ) of 0. 7 ng mL-1 and with a standard deviation of 0. 9 %. © 2012 Springer-Verlag Wien.
