The kinetics and mechanism for the ion-exchange processes like Mg(II)-H(I), Ca(II)-H(I), Sr(II)-H(l), Ba(II)-H(I), Ni(II)-H(I), Cu(II)-H(I), Mn(II)-H(I) and Zn(II)-H(I) at different temperatures using approximated Nernst-Plank equation under the particle diffusion controlled phenomenon were studied for the polypyrrole zirconium titanium phosphate nanocomposite cation exchanger. TEM proves the formation of the nanocomposite cation exchanger. Some physical parameters, i.e. fractional attainment of equilibrium U(tau), self-diffusion coefficients (D-0), energy of activation (E-a) and entropy of activation (Delta S degrees) have been estimated. These results are useful for predicting the ion exchange process occurring on the surface of this cation-exchanger. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
