     in this study, bi2o3 with band gap energy of 2.6 ev was coated on a ti disk and used in a rotating disk reactor to treat 10 mg l−1 rhodamine b (rb) solution under uv and visible light irradiation. the effects of different inorganic anions (including co2-3, s2−, so2-4, f and cl) were investigated and the results shown that the color removal efficiency could be greatly improved in the presence of cl. rb adsorption capacity could be enhanced when cl was added and rb could further be degraded due to indirect dye self-photosensitization under visible light irradiation. the radicals generated during the reaction were detected by adding radical trapping agents and other experimental conditions like cl concentration, rotating speed and ph of the process were investigated and optimized.
