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.
