Cation Exchange Capacity of Kaolinite

open access: yesClays and Clay Minerals, 1999
AbstractExperimental cation exchange capacities (CEC) of kaolinites were determined and compared to theoretical calculations of CEC. The comparison reveals that the exchangeable cations occur mostly on the edges and on the basal (OH) surfaces of the mineral.
