Sažetak
The sorption of lead from water solutions onto natural and iron (III)-modified zeolite was examined as a function of pH. Pseudo-second-order kinetic analyses were performed to determine the rate constant of sorption. Rate constants for lead sorption on zeolites are highest at pH = 4.24 and they are 0.381 and 0.201 for natural and iron (III)-modified zeolite respectively. The results showed that there are no significant influence of pH on sorption of Pb2+ ions on natural zeolite and iron (III) modified zeolite in pH range from 2.19 to 4.24, and the best pH value of the system to remove Pb(II) from aqueous solutions using zeolites is between 3.63 and 4.24.
