Abstract
This article reports studies on the coagulation of kaolin(from Wuxian, Jiangsu, China) on various red tide organisms, and the observation for the first time that the coagulation of kaolin is much greater than that of montmorillonite so that kaolin is a more effective, clay for removing red tide organisms. The authors’ theoretical explanation and analysis by a mathematical-physical model prove that compared to montmorillonite, kaolin has greater attraction for organism cells and therefore greater coagulation capability. This project’s studies on the effects of pH and acid-treatment show that the acid-treatment does not have much influence of the kaolin system; whereas the effect of pH on the kaolin system is the same as that on the montmorillonite system.
