中文摘要：

(acrylo-amidino 乙烯胺)(PAEA ) Poly， nanofiber 膜被联合 electrospinning 技术和随后的化学修正综合了。膜被用来从水的答案作为(V) 搬迁。吸附动力学，平衡等温线，和 pH 效果在批实验被调查。运动模型与试验性的数据同意很好的兰米尔等温线和假秒顺序。PAEA nanofibers 是有效的为作为在 pH 的(V) 吸附 3。试验性的结果证明 PAEA nanofibers 与的最大的吸附能力因为(V) 是 76.92 mg g1，它比 PAEA microfibers (27.62 mg g1 ) 的高得多。PAEA nanofibers 的吸附率由于它的更高特定的表面区域是比 PAEA microfibers 的快的。PAEA nanofibers 能为移动被用作有效吸附物作为在水的答案的(V) ，由于高吸附，能力和短吸附预定完成平衡。

英文摘要：

Poly（acrylo-amidino ethylene amine） （PAEA） nanofiber membranes have been synthesized by combining the electrospinning tech- nique and subsequent chemical modification. The membranes were used to remove As（V） from aqueous solution. The adsorp- tion kinetics, equilibrium isotherms, and pH effect were investigated in batch experiments. The Langmuir isotherm and pseudo second-order kinetic models agree well with the experimental data. The PAEA nanofibers are effective for As（V） adsorption at pH 3. Experimental results showed that the maximum adsorption capacity of the PAEA nanofibers with As（V） is 76.92 mg g-l, which is much higher than that of the PAEA microfibers （27,62 mgg-1）. The adsorption rate of PAEA nanofibers is faster than that of PAEA microfibers due to its higher specific surface area. The PAEA nanofibers can be used as an effective adsorbent for the re- moval of As（V） in aqueous solution due to high adsorption capacity and short adsorption time to achieve equilibrium.
