    Kinetic investigations show that most of the soluble aluminum is extracted even before reaching the process temperature of 280 °C after approx. 90 min heating time. But there is still a slight increase in aluminum recovery during the first 60 min of leaching, obviously indicating that the dissolution of aluminum silicates takes time.

    Effect of Different Kinetic Factors on the Thermochemistry of .

    These kinetic parameters not only have effect in the kinetics of the attack reaction but also have a considerable effect on the thermochemical aspect. We will not stop at the stage of the thermodynamic study of the sulfophosphoric attack reaction. Our approach in the future work is to study the kinetic aspect of this last reaction by varying the different kinetic factors influencing the reaction attack.

The distribution coefficients of U, Th and lanthanides in EDTA, citric acid and nitric acid media signify the possible separation of each element from the others. The salinity did not significantly affect the ability of Si-HA to extract Th and U. The adsorbent stability and reusability were also assessed through four
