Abstract
The influence of temperature on the kinetics of dissolution of the amo rphous 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(-1) NaOH solut ion. The change in the dissolution temperature does not affect the mec hanism of the dissolution, only the rates of the forward and back reac tions. Activation energies of the forward and back reactions were dete rmined from the corresponding Arrhenius plots.
