Fourier-transform infrared spectroscopy analysis of mechanochemical transformation kinetics of sodium carbonate to bicarbonate
Abstract
<jats:p>During mechanical activation, qualitative changes that can produce variousphenomena occur in the material. In this study, anhydrous sodium carbonatewas mechanically activated for 2, 7, 14, and 28 minutes in a vibro mill at afrequency of 3000 oscillations per minute. After activation, four series ofactivated samples were stored in the air at room conditions for 31 days(relaxation period). To monitor the kinetics of the transformation processof activated sodium carbonate samples, i.e. the mechanism of sodiumbicarbonate formation during relaxation, Fourier-transform infrared (FTIR)spectroscopy analysis was used. FTIR testing was performed as a function ofrelaxation time for all four series of samples, with characteristic groupsobserved: CO32-, HCO3- and OH-. The obtained results provided kineticsparameters for the transformation of sodium carbonate into sodiumbicarbonate due to the chemisorption of moisture and carbon dioxide from theatmosphere.</jats:p>
