and scanning electron microscopy. Methylene blue solution was treated with water-bath in the presence of hydrogen peroxide and ammoniojarosite. All kinds of influencing factors were investigated. The experimental results show that methylene blue can be more efficiently removed in acid media, and the removal rate increases with the increase of concentration of H2O2. The removal rate of 100 mL MB......
