In presented paper removal of lead ions from water solutions by the natural and Fe(III)-
modified zeolite encapsulated with alginate was investigated. Experiments were performed for
the initial lead concentrations in the range from 330 to 3100 mgPb(II)/dm3 and for three
temperatures: 25, 40 and 60oC. Results showed increase of adsorbed amount of lead with
increasing temperature and the initial lead concentrations. Much better removal of lead was
obtained with Fe(III)-modified zeolite encapsulated with alginate. The maximal removed
amounts of lead obtained for highest initial concentration were: 103, 113 and 124 mg/g for NZA
and 137, 153 and 173 mg/g for FeA at 30, 40 and 60oC, respectively. Obtained results were
fitted with Freundlich and Langmuir model, and for all temperatures the best fits were obtained
with Freundlich model (R2>0.97).
