A radioactive fluid waste polluted with cesium-137 from Al-Tuwaitha site -south of Baghdad-Iraq is used in this paper. Commercial zeolite is used as a sorbent material in the present work for the removal of radioactive cesium-137. The removal efficiency for radioactive liquid was 96.43 % with 2 h mixing time, 0.04 g sorbent mass and pH=6.8 and at room temperature. The Freundlich and Langmuir isotherm models were found to represent the experimental results well and these results are more consistent with Freundlich model than Langmuir model.
