Sodium carbonate was mechanically activated for 7 minutes in a vibro mill at a frequency of 3000 oscillations per minute. Activated samples were stored in the air at room conditions for 31 days. To monitor the kinetics of the transformation process of sodium carbonate to bicarbonate, Fourier-transform infrared (FTIR) spectroscopy analysis was used and was performed as a function of relaxation time for characteristic groups observed: CO3 2–, HCO3 – and OH–. The obtained results provided kinetics parameters for the transformation of carbonate into bicarbonate as a result of chemisorption of moisture and carbon dioxide from the atmosphere.
