A crosslinked polyester resin containing acrylic acid as functional groups was synthesized and characterized by using FT-IR method. Adsorption behavior of strontium ions on the synthesized polyester resin was investigated as a function of sorptive concentration, time, temperature, and pH by using ICP-OES measurements. Adsorption data were analyzed by the modified Freundlich, Elovich, pseudo-first order and pseudo-second order kinetic models, by the Freundlich, Langmuir and Dubinin–Radushkevich isotherms and by the thermodynamic parameters such as enthalpy (∆
H
°), entropy (∆
S
°) and free energy change (∆
G
°).
