Abstract
The ion exchange kinetic among sulphonated polystyrene membranes Permion 4010 and hjdroxyphenylethanolamine derivatives has been investigate. The kinetic of ion exchange process has been studied by differential method, calculating the order about concentration in the equilibriun direct process. The logarithmic representation of initial rates against initial concentration gives as result a frrsth order for this reactions. Then the rate constants at different temperatures as well the termodynamic parameters have been calculated.
