| 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２２～２５Ａ非晶固体。它是由有序周期（ｒ、）≌１２－１４Ａ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」，「ＡｌＯ４」（０＝Ｏ，ＯＨ）和八面体「ＡｌＯ６」（Ｏ＝Ｏ，ＯＨ）组成的。Ｄ／ｒ１＝２～３，因此ＴＸ２

| Abstract: | The structure IPF(Inorganic Polymer Floccutant) TX203 has been studied using the wide angle X-ray scattering(WAXS) and radial distribution function (RDF). WAXS and RDF show that TX203 is an amorphous solid with ordering size (D) of about 22 - 25A. It is made up of medium range ordering domains with approximate periodicity (r1 ) of 12 - 14A, 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. |
