Abstract:	The adsorption desorption rate of H⁺ ions on α-aluminium hydroxide has been investigated as a function of pH and temperature from aqueous electrolyte solution of ZnCl₂. It is observed that the protonation of the α-Al(OH)₃ surface is more dominant at pH 5 than the adsorption of Zn²⁺ while at pH 7 the adsorption of Zn²⁺ ions predominates. The experimental results are explained with the help of the film diffusion equation. The values of activation energies are found to increase with the increase in temperature of the system
