采用溶胶-凝胶法合成了纳米氧化铁,研究了合成条件,并采用TEM对产品进行了表征,测得产品的平均粒径为20-30nm.研究了纳米级氧化铁对Cr（Ⅵ）的吸附.在pH=3.0,吸附比为3.5×10-6:1×10-2（g/g）时,平均吸附效率为95.98％,最大吸附量为398.3μg Cr（Ⅵ）/g.采用2mol/LNaOH可完全洗脱纳米氧化铁所吸附的Cr（Ⅵ）,测定了回收后的纳米氧化铁对Cr（Ⅵ）的吸附效率,结果表明纳米级氧化铁可循环使用,这将为环境污水中Cr（Ⅵ）的治理及研究纳米材料的吸附行为提供参考.     

Atom transfer radical polymerization directly from poly(vinylidene fluoride): Surface and antifouling properties

The direct preparation of grafting polymer brushes from commercial poly (vinylidene fluoride) (PVDF) films with surface‐initiated atom transfer radical polymerization (ATRP) is demonstrated. The direct initiation of the secondary fluorinated site of PVDF facilitated grafting of the hydrophilic monomers from the PVDF surface. Homopolymer brushes of 2‐(N,N‐dimethylamino)ethyl methacrylate (DMAEMA) and poly (ethylene glycol) monomethacrylate (PEGMA) were prepared by ATRP from the PVDF surface. The chemical composition and surface topography of the graft‐functionalized PVDF surfaces were characterized by X‐ray photoelectron spectroscopy, attenuated total reflectance/Fourier transform infrared spectroscopy, and atomic force microscopy. A kinetic study revealed a linear increase in the graft concentration of poly[2‐(N,N‐dimethylamino)ethyl methacrylate] (PDMAEMA) and poly[poly(ethylene glycol) monomethacrylate] (PPEGMA) with the reaction time, indicating that the chain growth from the surface was consistent with a controlled or living process. The living chain ends were used as macroinitiators for the synthesis of diblock copolymer brushes. The water contact angles on PVDF films were reduced by the surface grafting of DMAEMA and PEGMA. Protein adsorption experiments revealed a substantial antifouling property of PPEGMA‐grafted PVDF films and PDMAEMA‐grafted PVDF films in comparison with the pristine PVDF surface. © 2006 Wiley Periodicals, Inc.
