Abstract
Coagulation of red tide organism cells with clays is discussed in theory and the effects of some factors on it are studied. A quantitative model is presented which describes how the coagulation varies with pH in solution. According to the model, within the pH-range between\(pH_{zpc_a } \) and\(pH_{zpc_b } \),V R is negative and the coagulation is strong and strongest at\(pH = \left( {pH_{zpc_a } + pH_{zpc_b } } \right)/2\). It is also demonstrated that when the diameter of clay particles is close to that of cells, the collision probability is low, resulting in weaker coagulation. The model results have been corroborated by experiments and so are scientific and theoretical bases for application.
