WebAbstract Biological desulfurization processes of landfill gas yield an enormous amount of biologically produced S (BPS) as a byproduct. Capability of BPS to remove Cd 2+ from aqueous solutions was tested and its removal efficiency was compared to that of granular activated carbon (GAC). Elemental sulfur is used mainly as a precursor to other chemicals. Approximately 85% (1989) is converted to sulfuric acid (H2SO4): 1⁄8 S8 + 3⁄2 O2 + H2O → H2SO4 In 2010, the United States produced more sulfuric acid than any other inorganic industrial chemical. The principal use for the acid is the extraction of phosphat…
