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 Boron-containing polysilicate ferric sulfate (PFSSB) was analyzed by chemical complexometric titration, transmission electron microscopy and infrared spectroscopy. The results show that PFSSB is a new polymer formed by the interaction of polysilicic acid, Fe3 +, Fe3 + and B3 +. Its special banded structure makes it more stable than polysilicate (ellipsoidal structure), polysilicon Sour iron sulfate (shrimp nodular structure) has better stability and coagulation properties.
