In the process of biological desulfurization of gases from landfills, huge amounts of biologically produced Sulfur (BPS) were produced as by-products. A study was conducted to find out the possibility of using it as an adsorbent for Pb<SUP>2+</SUP>. BPS was subjected to an adsorption test in an aqueous solution in the presence of Pb<SUP>2+</SUP> and compared with the removal efficiency of granular activated carbon (GAC), which is mainly used as an adsorbent for heavy metal. As a result of the Pb<SUP>2+</SUP> removal experiment using BPS, it was a two-step process in which 54.5% of the initial Pb<SUP>2+</SUP> was removed within 5 minutes by fast initial adsorption followed by slow adsorption. As a result of the isotherm adsorption experiment, the Pb2+ adsorption to BPS was fitted the Langmuir isotherm model, and the maximum adsorption capacity of BPS (175.4 mg g<SUP>-1</SUP>) was about 3 times higher than that of GAC (67.11 mg g<SUP>-1</SUP>). The data from XPS demonstrated that the main adsorption mechanism was the complexation of Pb<SUP>2+</SUP> with the sulfide in the BPS. Therefore, it was confirmed that BPS has sufficient value to be recycled as a new adsorbent for Pb<SUP>2+</SUP> removal in wastewater.
