Zeolite A adsorbent has been prepared for adsorption of Sr2+ and Cs+. The present adsorbent has sufficient adsorption ability for both ions, of which adsorption achieved within 1 h. The adsorption mechanism for both ions is Langmuir type, and the maximum adsorption amount at equilibrium pH of 4.00 are 3.32 mmol/g for Sr2+ and 1.66 mmol/g for Cs+, respectively. Since the pH dependencies of the adsorption of Sr2+ and Cs+ are different, selective separation of Sr2+ and Cs+ is expected to be achieved.
