Аннотация
The kinetic performance of strongly acidic sulfonate cation exchange resins towards ions of alkali metals (Li, K, and Na) under static conditions has been examined. Kinetic parameters of the sorption process, in particular, half-time of exchange and maximum possible flow rate of solution through the sorption column in the dynamic mode have been determined. The sorption kinetics mechanism has been explored. Recovery of the elements from model unicomponent solutions on strongly acidic cation exchange resins is satisfactorily described by pseudo-second-order kinetic model.
