Estimation of Saponite Sorptive Properties with Regard to Fluoride Ions

摘要

Equilibrium sorption of fluoride ions by saponite has been investigated at pH of the equilibrium solution characteristic of natural waters. A theoretical model of the equilibrium sorption of fluoride ions by saponite exchange groups selective with regard to such ions was proposed. The total exchange capacity of the specified exchange groups and their equilibrium constant were also found.
