研究了不同碱化度、不同铝铁比的聚合氯化铝铁（ＰＡＦＣ） 溶液的ｐＨ 驰豫、电导率变化，可见光谱及絮凝效果等物理化学性质。提出了Ｂ≥１ ．５ 后，Ａｌ（ Ⅲ） 、Ｆｅ（ Ⅲ）多核羟合配离子迅速交叉共聚形成高聚物的假设。通过稳定性观察，作出了对ＰＡＦＣ 工业化生产具有指导意义的稳定性—ｐＨ（Ｂ） —ｎＡｌ／ｎＦｅ 关系图。
The physicochemical properties, such as pH relaxation, conductivity change, visible spectrum and flocculation effect, were studied in different aluminum and aluminum alkalis. Proposed B ≥ 1. 5, the assumption that Al (Ⅲ) and Fe (Ⅲ) polynuclear complex ion rapidly cross-copolymerize to form polymer. Through the observation of stability, the stability-pH (B) -nAl / nFe diagram, which is of guiding significance for the industrial production of PAFC, has been made.
