Abstract

In this work, the kinetic parameters of Co2+ ion adsorption by α-C2SH were determined. α-C2SH was synthesized under hydrothermal conditions at 175 °C, when the duration of isothermal curing was 24 h and the molar ratio of primary mixture was CaO/SiO2 = 1.5. This research allows us to state that the adsorption reactions proceed according to the chemisorption process. In order to determine adsorption kinetic parameters, kinetics models have been developed and fitted for these reactions. Additionally, it was determined that adsorbed Co2+ ions have a significant influence on the stability of α-C2SH. These results were confirmed by XRD, STA, and atomic absorption spectroscopy methods.
