The efficiency of the natural and Fe(III)-modified zeolite for Pb2+ removal at different initial
pH (2.5, 4.2 and 5.0) was investigated. For initial pH 2.5, for all concentrations and both
adsorbents ion exchange of inorganic cations in zeolites with lead ions, together with uptake of
hydrogen occurred. For initial pH 5.0 it was determined that at lower initial concentrations of
lead ion, ion exchange occurred, while at higher initial concentrations beside these processes,
chemisorption of lead ions occurred on both adsorbents. Preliminary experiments on waste
water obtained after flotation process in facility of lead and zinc mine showed that waste water
treatment with both adsorbents reduced the content of all investigated heavy metal cations.
However, better removal was achieved with the Fe(III)-modified zeolite.
