摘要：

To explore the adsorption behavior between 4A zeolite and simulated nuclide Sr2+ the orthogonal project was carried out to investigate the adsorption ability of 4A zeolite on simulated nuclide Sr2+ under the different conditions (reaction time adsorption temperature pH). The XRD patterns of 4A zeolite after adsorption presented a phenomenon that diffraction peak became lower than that before adsorption. The saturated adsorption quantity of 4A zeolite was calculated to be 151.17mg/g under the different initial concentration. The sequence of three impact factors was adsorption time > pH > reaction time. The best adsorption condition was that pH 11.5 adsorption temperature 35 degrees C reaction time 5h. It turned out that the initial concentration of simulated nuclide Sr2+ impacted the adsorption process heavily.
