Based on new physicochemical and probability concepts concerning rapid coagulation of lyophilic disperse systems (LDS), a theory that correlates this phenomenon with the amount and state of metal ions is developed. The amount of these ions decreases inversely proportionally to the difference between the charge of the metal ion and the number of OH groups in its inner coordination sphere in coagulation according to a multilayer adsorption mechanism. For a dose of metal ions less than or equal to the concentration of the initial LDS, coagulation takes place according to a multilayer adsorption mechanism.
