    Study on the activation of calcium montmorillonite (Ca-MMT) by sodium cations
    (2016) Kurleto-Kozioł, Żaneta; Grabowska, Beata
    The results of spectral research (IR, UV-Vis) on the activation process of calcium montmorillonite Ca-MMT by sodium cations are presented in this article. The modifications of Ca-MMT were carried out by a modifier in the form of sodium carbonate by keeping different times of activations. On the basis of received sodium modifiers MMT (Na-MMT) analytical cycle of research was done, including structural (IR) and spectrophotometric (UV-Vis) research, in order for the designation of ion exchange ability (CEC). There was observed that the method of processing modification (changing activation time) does not affect on ion exchange ability Na-MMT. Application of modified MMT used as a binding material in greensand will be described in the next part of our planned research.
