【Abstract】 Based on the equilibrium equation and kinetic mechanism studied about an ion exchange reaction, a mathematical model, which can simulate the working behavior of an ion exchange column, was developed in this paper. With the integrated partial differential first order equations for two variables, the mathematical model was analytically solved using the Laplace transferring method. Model results match successfully with experimental data. It is noteworthy that the mathematical model will be useful in predicting the working behavior of an ion exchange column, the relationship between water treatment time and extent of an ion exchange process, so as to guide the ion exchange unit operation quantitatively.更多还原
