• 摘要：仅以IPF颗粒物水溶液的相互作用为例,对混凝研究中二界面过程化学领域的进展加以介绍.研究结果表明,经过预制的聚合铝在混凝过程中表现出较好的形态稳定性,而传统混凝剂则强烈地受溶液化学过程,尤其是溶液pH值的影响.

• Abstract：The interfacial process chemistry of the aquatic particle, which forms an important content and theoretical basis for the research and development of coagulation technique, plays a significant role during coagulation process. The interation of inorganic polymer flocculant(IPF)-particle-aqueous solution was discussed as an example. The experimental results showed that the pre-formed PACl exhibits relative speciation stability during coagulation, while the traditional metal sAl_Ts are affected strongly by the solution chemical processes, especially the pH. The hydrolyzed species adsorb and deposit strongly on the particle interface,which causes the coagulation. The monomer species coagulate particles through transformation into polymeric and colloidal species.
