Abstract: A study of the adsorption of alkaline anions on lead (IV) oxide (PbO2) used as cathode material in dry cell has been carrying out. The absorption method by potentiometric titrations were adopted for different anions at four different concentrations of the anions in augment solution. The results of the analysis obtained showed that lead (iv) Oxide (PbO2) can be used in dry cell as a depolarizer when blended with alkaline anions particularly the sulphate (SO42-) ion as compared with NO3-, Cl- and Br- ions, respectively some graphs were plotted in addition to some fear ones necessary for both the determination of the surface areas of PbO2. Also the adsorption of alkaline anion on PbO2 is in accordance with Longmuir Freundlich and Tamkin isotherms.
