Sažetak
In this paper, results of lead sorption by the natural and its iron (III)-modified zeolite are presented. It was determined that, for both zeolites lead sorption increased with increasing the initial concentration of lead in solution. Much higher sorption of lead was achieved with the iron (III)-modified zeolite. The results were fitted to the Langmuir and Freudlich sorption isotherm. The best fit of experimental data was achieved with the Freundlich sorption isotherm (correlation coefficient >0.93). From Langmuir isotherm, maximally sorbed amount of lead was 0.318 and 0.642 mmol/g for the natural and iron (III)-modified zeolite, respectively.
