초록

The adsorption characteristics of Sr and Cs ions were investigated by using PS-zeolite beads prepared by immobilizing zeolite with polysulfone (PS). The adsorption kinetics of Sr and Cs ions by PS-zeolite beads was described well by the pseudo-second-order model. The maximum adsorption capacities of Sr and Cs ions calculated from Langmuir isotherm model were 65.0 mg/g and 76.4 mg/g, respectively. In the binary system of Sr ion and Cs ion, the adsorption capacities of each ion decreased with increasing mole ratio of mixed counterpart ion, and Cs ion showed the higher hinderance than Sr ion. We found that thermodynamic properties of Sr and Cs ions on absorption reaction were spontaneous and endothermic at 293 to 323 K.
