Abstract
In this study, the removal of zinc ions In (II)j from agUeous solutions by using
agricultural by-product of co conut coir fir activated carton preparation was investigated.
*1 he effects of initial solution pi I, initial metal ion concentration and amount of adsorbent
on the adsorption process were also examined. The diflcrcnt kinetic modeling analysis of
the I
.
lovich, pseudo-first order, pseudo-second order, intraparticlc diffusion, mass
transfer and intraparticic diffusivity equations will he used to analy,. c the kinetic data for
to (II) ion adsorption. The kinetic parameters including rate constant are determined at
different initial metal ion conccnirntion, piI and the amount of adsorbent. The I-angmuir
and Freundlich adsorption isotherm models are used to describe the experimental data
and I. angmuir model showed a better correlation cocflicicnt. The coconut coir was found
to be a metal adsorbent as cflcctive as activated carbon.
