中文摘要：

采用“准一步法”，制备端羟基超支化聚合物（HPAE），研究了HPAE在水溶液中对铁、铝离子的吸附去除，探讨了其吸附过程的热力学：在293-313K条件下，Langmuir等温方程呈现较好的拟合，不同温度下的△H〉0、△G〈0、△S〉0，表明该吸附反应是吸热、自发的、熵增的过程。

英文摘要：

Hyperbranched polymer was prepared using quasi-one-step method. The adsorption of Fe3＋ and Al3＋ in water by HPAE was also studied. And the thermodynamics of the adsorption process was discussed. Langmuir isotherm equation fit well while △H 〉 0, △G 〈 0, △S 〉 0 at different temperature from 293 K to 313 K. It was indicated that the adsorption reaction was endothermic, spontaneous and entropy production process.
