Study on the Adsorption of Fe~(3+),Al~(3+) in Water by Hyperbranched Polymer and its Thermodynamics Behaviour

Hu Yanxin1,Zheng Shujie2,Chang Yongsheng2(1.Key Laboratory of Aids Chemistry and Technology for Light Chemical Industry,Ministry of Education,Shaanxi University of Science and Technology,Xi'an 710021;2.Changing Oilfield Company Gas Production plant No.4,Xi'an 710021,China)  
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 ΔH﹥0,ΔG﹤0,ΔS﹥0 at different temperature from 293 K to 313 K.It was indicated that the adsorption reaction was endothermic,spontaneous and entropy production process.
