摘要：
In this study, phosphorus-containing resin carbon (PRC) was prepared by freeze-drying and carbonization using sodium hexametaphosphate and a polymeric absorbent resin as raw materials. The adsorbents were characterized using infrared spectroscopy and scanning electron microscopy. The effects of pH value, adsorption time and temperature on uranium adsorption by PRC were investigated via static experiments. The adsorption process was analyzed via kinetic and isotherm models. The results showed that the equilibrium time of uranium adsorption by PRC was approximately 60 min, and the adsorption amount of uranium (VI) reached 909 mg g−1 at a pH of 6.0 and temperature of 313.15 K.
