螯合金属离子的腈纶纤维的制备及性能

Preparation and Properties of the Polyacryloniyrile Fiber Chelating Metal ion

以腈纶纤维 (PAN)为原料 ,与羟胺溶液反应 ,将纤维侧链上的部分腈基转化为偕胺肟基 ,制备一系列不同偕肟含量的腈纶纤维 (L)。再以此分别与FeCl3、NiCl2 、CuCl2 、Pb(Ac) 2 反应 ,得到 4个系列螯合了不同金属含量的腈纶纤维 ,测定其中的金属含量、纤维的表面形态、断裂强力以及各自的回潮率。

A series of chelating fiber containing amidoxime group was prepared by the reaction of PAN with NH_2OH at different time of the reaction.The fiber was reacted respectively with FeCl_3,NiCl_2,CuCl_2,Pb(Ac)_2 solution,four series of PAN chelating metal ion were prepared. Metal content,surface shape,breaking strength and reverse wetting ratio of the PAN chelating metal ion fiber were examined
