Wastewater management covers various techniques developed to provide purified water that would
do minimum harm to the environment. Applying adsorption leaves a saturated adsorbent that should
be regenerated or stabilized so it can’t release pollutants into the environment. Lead, one of the most
toxic pollutants, can be efficiently removed utilizing the adsorption process. After the consecutive
adsorption and desorption processes, the lead must be processed to significantly reduce and prevent
the risk to human health and environmental pollution. As one of the most efficient technologies for
treating this toxic pollutant, stabilization has been tested by converting a desorbed lead to its salt leadphthalate
(LP). Obtained LP is used as a component in the production of construction materials and
composites with unsaturated polyester resins (UPR). A standard leaching test (Toxicity Characteristic
Leaching Procedure - TCLP) was performed to determine the toxicity of the waste materi...al used as
an additive. The concentration of leached lead from the construction material with the addition of
Ca(OH)2 can be as high as 54 mg/L, which significantly exceeds the permitted limits. After adding
cement, lead concentration is lower - 13 mg/L. The acquired results from the sample with UPR show
that the concentration of released lead is as low as 0.01 mg/L. Such results indicate complete
crosslinking of the UPR and strong binding of the lead ions. Applying the S/S technique together with
the utilization of UPR would be an environmentally friendly operation and easily applicable
procedure for stabilizing Pb2+.
