• 摘要：羟基聚合物的形态转化是无机高分子絮凝剂的核心问题。其形态学应包括研制、生产和应用三方面内容。铝的羟基聚合物形态主要有六员环连续模式和聚十三铝聚集模式两类论点。形态控制参数应以水解度和碱化度并用。Ferron逐时络合比色法可作为形态分类常规测定方法。聚十三铝的生成条件是提高聚合铝絮凝效能的重要研究方向。它具有相对稳定性,但在自发水解中很难生成。羟基聚合物与颗粒物的相互作用机理特征介于传统混凝剂和有机高分子絮凝剂之间。

• Abstract：The transformation of species for hydroxyl polymer is a key problem of inorganic polymer flocculants. Their morphology should consist of the processes in research and development, production and application. There are two main aspects of the speciation for aluminum polymer: hexagonal rings model and tridecameric Al model. The multi functonal parameter hydrolysity is more useful than basicity. Ferron timed complexation spectroscopy is a practical method for speciation of hydroxyl polymer. The formation and stability of Al₁₃ are important research topics. The mechanism of flocculation for inorganic polymer is at the position between the traditional coagulants and the organic flocculants.
