Coagulation of red tide organism cells with clays is discussed in theory and the effects of some fac-tors on it are studied.A quantitative model is presented which describes how the coagulation varies withpH in solution.According to the model,within the pH-range between pH_(zpc_a)and pH_(zpc_b),V_R is negativeand the coagulation is strong and strongest at pH=(pH_(zpc_a)+pH_(zpc_b))/2.It is also demonstrated that whenthe diameter of clay particles is close to that of cells,the collision probability is low,resulting in weakercoagulation.The model results have been corroborated by experiments and so are scientific and theoreticalbases for application.
Coagulation of red tide organism cells with clays is discussed in theory and the effects of some fac-tors 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 = (pH_ (zpc_a) + pH_ (zpc_b)) / 2.It is also demonstrated that whenthe diameter of clay particles is close to that of cells, the collision probability is low, resulting in weakercoagulation.The model results have been corroborated by experiments and so are scientific and theoreticalbases for application.
