| 摘 要： | This article deals with the interaction of zinc with δ-MnO2,γ-MnOOH and manganite existing in natural water systems. The mechanism of the reaction has been studied in detail. From the fact that the "ratio of ion exchange (%)-pH" graph is an "S shaped" curve, it is possible to deduce that the chemical reaction is of the nature of cation exchange. And since the pH range of ion exchange = 4, it is possible to further deduce that the reaction can be explained by the mechanism of monovalence cation exchange.The main result of this article is the discovery of a new type of isotherm which has not been mentioned in previous literature here and abroad. This isotherm cannot be represented by any presently available adsorption isotherm equations in marine chemistry. The characteristics of this new type of isotherm are as follows: the isotherm has two "knees" and three "plateaus", the heights of these three "plateaus" are in the ratio 1:2:3. In order to explain theoretically our new isotherm, this article suggest
