| Abstract: | The kinetics of red tide organism (Prorocentrum minimum) coagulation withclays is studied in Apr.-Sept., 1992. The effects of different kinds and concentrations of clays, of the second component PACS (polyhydroxy aluminum chloride) added in clays, and of pH on the coagulation rate are examined. A model of the kinetics of red tide organisms coagulation with clays is established, which theoreticallyaddresses the factors affecting the coagulation rate and suggests ways to increase thecoagulation rate, The results show that the coagulation rate is more rapid in thesystem of kaolin than in that of montmorillonite, and that the kinetics equation forthese systems describeds bimolecular reaction, in which the rate constant is variedin the process of coagulation. The potential energy and radius of interaction between clay particles and organism cells are the major factors controlling the coagulationrate. It is found that the increase of clay concentration can accelerate coagulation,but is not the most effective way. Adding PACS in clays appears to be the mosteffective way of increasing the coagulation rate. |
