Removal of arsenite and arsenate in sulfuric acid solutions were investigated with PbS, ZnS, FeS and CuS at 298K. Both arsenic species were removed by PbS, ZnS and FeS. Especially, PbS was most effective to remove arsenic species from the solutions. The removal of the arsenic species by PbS depends on the sulfuric acid concentration and is minimum at sulfuric acid concentrations around 0.01 kmol m-3. Thermodynamic analysis of the experimental results and XRD and SEM-EDX analysis of the solid residue suggest that the removal of the arsenic species by PbS is due to both arsenic adsorption on PbS surface and precipitation of As2S3(am) by the reaction of the arsenic species and H2S generated by PbS.
