Ion-exchange kinetics of alkaline metals on the surface of carboxymethyl cellulose Sn(IV) phosphate composite cation exchanger

Ali Mohammad, Mohd Imran Ahamed, Arshi Amin, Inamuddin

Approximated Nernst-Plank equation was used to study the kinetics and mechanism for the ion-exchange processes like Mg2+-H+, Ca2+-H+, Sr2+-H+ and Ba2+-H+ on the surface of carboxymethyl cellulose Sn(1V) phosphate composite nano-rod like cation-exchanger. The kinetics of exchange was favoured under the particle diffusion controlled phenomenon. Some physical parameters i.e. fractional attainment of equilibrium U(), self diffusion coefficients (Do), energy of activation (Ea) and entropy of activation (ΔS*) have been estimated.
