用本文提出的方法计算的参数B = OH/Fe比表征了Fe（III）在酸碱作用下的水解-聚合-沉淀过程。溶液的B分类在pH随时间的变化、吸收光谱、化学形态和溶解行为等方面具有自洽性。预形成的B型Fe（III）水溶液在0.5-1.0范围内对高岭土悬浮液具有最佳的凝聚能力。
The hydrolysis-polymerization-precipitation processes of Fe (III) in solution with acid-base addition can be characterized by a parameter B∗= OH/Fe ratio calculated by a method suggested in this paper. The classification of solutions by B∗ is self-consistent in their performances as pH evolution with time, absorption spectrum, chemical speciation and coagulating behaviors. The preformed Fe (III) solution of type B∗= 0.5–1.0 exhibited the optimum ability to coagulate kaolinite suspensions.
