中文摘要	实验研究了去除水中全氟辛基磺酸(PFOS)的纳米吸附剂的制备方法,并对其性能进行表征。研究结果表明:单体(4-乙烯基吡啶)含量对吸附剂去除PFOS的效果影响显著;而聚合状态、聚合液含水率、有机溶剂和交联剂的种类仅对吸附剂形态和比表面积有一定影响,但对吸附剂去除PFOS的效果影响不大。红外光谱揭示了单体和交联剂的有效聚合,ζ电位的测定则证实了单体和PFOS是由于静电作用而结合。; The paper presented methods and results of preparation and characterization for a new nano-particle polymer adsorbent effective for removing PFOS(C8F17SO-3)from water.The experimental data demonstrated that the molar monomer(4-VP)/cross-linker ratio was the major factor affecting the adsorbent's capacity for PFOS;degree of polymerization,solvent/water of the reaction mixture,type of organic solvent(methanol and acetone)and cross-linker(TRIA and EGDMA)affected its shape and specific surface area more significantly than its PFOS capacity.The FTIR charts for the adsorbent showed evidence of effective polymerization of 4-VP and the cross-linker.The Zeta potential data suggested that removal PFOS at pH<6.3 was primarily due to chemical adsorption of PFOS anion on protonated pyridine group of the adsorbent N2.; 国家自然科学基金资助项目(No.50608045)
