Kinetics of Cation Exchange Capacity of Homoionic Sodium Form Nay Zeolite

Abstract

Batch experiments have been performed on samples of synthetic homoionic sodium form NaY zeolites to measure their cation exchange capacity (CEC) and the kinetic parameters associated the exchange process. The kinetic data of the ion exchange of homoionic sodium form NaY zeolite/ Ca aqueous solutions systems at different temperatures was best fitted to Pseudo second order kinetic model. The results indicated that diffusion is the only mechanism that describes mass transfer from the particle surface to the exchangeable site, and intraparticle transport is the only rate –limiting step in the process of cation exchange.
