In this study, poly(ε-caprolactone) electrospun nanofibers-copper hexacyanoferrate composite ion exchanger (PCL nanofibers–CuHCF) was prepared and used for the cesium ion removal from aqueous solution. The results showed that the obtained composite exhibited excellent performance for the removal of cesium ions. The influences of several variables such as temperature, pH, and contact time were evaluated in batch experiments. The thermodynamic study indicated a spontaneous and endothermic ion exchange process. The adsorption isotherm and kinetics of the PCL–CuHCF composite were evaluated, indicating monolayer chemisorption of the Langmuir type. The maximum sorption capacities by applying the Langmuir equation was 178.7 mg/g.
