Se(VI) was hard to remove from the aqueous media by using the conventional removal method, such as adsorption. Therefore, the removal of Se(VI) from the simulated wet FGD waters by use of bioreduction and TiO_2 photocatalytic reduction were investigated. When the bioreduction and photocatalytic reduction systems were attempted for a simple 0.5 mg/L Se(VI) solution, the reduction of Se(VI) to Se(0) precipitate actually occurrs and Se(VI) was effectively removed from aqueous media. However, the removal efficiency of Se(VI) was considerably inhibited by some co-existing anions, such as NO_3^- or SO_4^<2-> when these reduction methods were applied for the simulated FGD waters.
