摘要
采用化学络合滴定、透射电镜、红外光谱等方法对含硼聚硅酸硫酸铁 (PFSSB)的结构进行了分析。结果表明 :PFSSB是聚硅酸、Fe3+ 、Fe3+ 的水解聚合产物和B3+ 相互作用而生成的一种新的聚合物 ,其特殊的带状结构使其较聚硅酸 (椭圆体结构 )、聚硅酸硫酸铁 (虾节状结构 )具有更好的稳定性和混凝性能。
The structure of polymeric ferric silicate sulfate containing boron (PFSSB) was analyzed by chemical titration, transmission electron microscope and IR spectroscope.The results showed that PFSSB is a new polymer formed by the interaction of polysilicic acid,Fe 3+ and its hydrolyzate and B 3+ .Because of the special lacy structure of PFSSB,it excels polysilicic acid (spheroid mode) and polymeric ferric silicate sulfate (PFSS,crayfish mode) in stability and coagulating properties.
