Dissolution of Amorphous Aluminosilicate Zeolite Precursors in Alkaline Solutions Part 3.-lnfluenee of Temperature on the Dissolution Process

The influence of temperature on the kinetics of dissolution of the amorphous aluminosilicate precursor with an Si:Al molar ratio 1.178:1 has been studied by measuring the change in the Al and Si concentrations in the liquid phase during the dissolution in 0.2 mol/l NaOH solution. The change in the dissolution temperature does not affect the mechanism of the dissolution, only the rates of the forward and back reactions. Activation energies of the forward and back reactions were determined from the corresponding Arrhenius plots.
