| 摘要: 本文用广角度X射线散射(WAXS)和径向分布函数(RDF)方法对聚合硅硫酸铝钾TX203絮凝剂的结构进行了分析。WAXS和RDF分析指出:该絮凝剂是一种有序尺寸(D)约为22-25Å非晶固体。它是由有序周期(r1)=12-14Å的中程有序畴组成的。而这些有序畴又是由三种结构单元,即四面体[SO4],[AIO4](O=O,OH)和八面体[AIO6](O=O,OH)组成的。D/r1=2～3,因此TX203是一种低聚体。在TX203絮凝剂中Si有增强结构序性的作用。 |

| Abstract: The structure IPF(Inorganic Polymer Floccutant) TX203 has been studied using the wide angle X-ray scattering(WAXS) and radial distribution function (RDF).WAXSand RDF show that TX203 is an amorphous solid with ordering size (D) of about 22～25Å.It is made up of medium range ordering domains with approximate periodicity (r1) of 12～14Å, and these domains are composed of three kinds of structural unit: tetrahedra [SO4],[AlO4](O = O, OH) and octahedron [AlO6](O = O, OH).D/r1 = 2～3, hence,TX203 is a low polymer.The adding of Si can enhance the structure ordering in IPF. |
