电子显微照片证实的新研究结果表明，与以前认为的相比，zeta电位对凝固效率的影响较小。电位决定离子的吸附和桥联比普遍持有的凝聚双层理论更好地解释了观察到的现象。还讨论了传统的罐试验和氢氧化铝溶胶。包括9个参考文献和插图。

New research findings verified by electron photomicrographs indicate that the efficiency of coagulation is less influenced by zeta potential than was formerly believed. Adsorption of potentialdetermining ions and bridging explain the observed phenomena better than the generally held double-layer theory of coagulation. Also discussed are the conventional jar test and aluminum hydroxide sol. Includes 9 references Illustrations.
