| 摘 要： | 含硼聚硅硫酸铁（PFSSB）是新近开发研制成的一种性能优良的无机高分子混凝剂。本文采用化学分析和X射线衍射法研究了该混凝剂成分间的相互作用情况，考察并分析了体系的pH驰豫及电学特征。结果表明，在体系中Fe^3 有其水解聚合产物、聚硅酸、B及SO4^2-离子等之间存在相互作用。这些相互作用的存在是PFSSB稳定和混凝性能提高的重要原因。 |
| 关 键 词： | 混凝剂 含硼聚硅硫酸铁 相互作用 pH驰豫 电学特征 化学成分 混凝性能 |

| Abstract: | Polymeric ferric silicate sulfate containing boron (PFSSB) is a highly effective inorganic polymeric coagulant studied and prepared recently. The components' interactions of PFSSB were studied by chemical analysis and X ray diffraction in this paper, and the variations of pH and electrical conductivity with aging time were also investigated and analyzed. It is found that some interactions exist among Fe 3+ and its hydro polymer products, polysilicic acid, B and SO 2- 4 . These interactions of components play an important role in enhancing stability and coagulating properties of PFSSB. |
| Keywords: | coagulant polymeric ferric silicate sulfate containing boron interaction variations of pH electrical conductivity |
