摘要：

The potential equation in the positive sol of aluminium magnesium hydroxide was deduced according to the model of constant surface charge density, and the potential curves in the NaBr solution were obtained. The studies of coagulation kinetics showed that the coagulation process of monovalent anions may be divided into a rapid and slow coagulation. The efficiencies in causing coagulation for monovalent anions followed the order Br->I->NO3- >Cl-, which didn' t correspond to the lyotropic series. The coagulation value of polyanion had a discrepancy with Shulze-Hardy law. The higher the cation valent was, the stronger the stabilization of sol was.
