摘要：
Equilibrium and kinetics have been studied for the sorption of samarium ions from samarium sulphate and nitrate solutions using naturally occurring mordenite-containing tuff. It has been established that samarium can be extracted at a quantitative level from dilute solutions. With increase in the solution concentration a decrease in the sorption capacity of tuff with respect to samarium ions is observed as the concentration increased. Kinetic parameters of sorption process have been determined.
