Abstract
The equilibrium and kinetics of samarium ion sorption from the solutions of its sulphate and nitrate on natural mordenite-containing tufa are studied. It is established that samarium is extracted quantitatively from the diluted solutions. With an increase in solution concentration, a decrease in sorption capacity of tufa with respect to samarium ions is observed. The kinetic parameters of sorption process are determined.
