摘要：

A comparative analysis of calculated acid-base equilibrium constants at the aluminum oxide(hydroxide)/solution interface is presented. The constants were obtained from the experimental pH dependences of the electrokinetic potential and potentiometric titration curves for Al2O3, AlOOH suspensions. The equilibrium constants and pH(zcp) values underwent displacement to the alkaline region as the degree of oxide hydration increased.
