| 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。

| Abstract: | 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. |
