【摘要】本文研究了用新生 Mn O2 作吸附剂 ,对水中直接耐晒蓝 (B2 RL)染料进行脱色的特性 ,探讨了影响吸附的因素 ,并给出适宜的吸附条件。在本试验条件下可使 B2 RL脱色率达 95 %。更多还原

【Abstract】 The decolorization characteristic of the fresh MnO 2 used as an absorbent to remove direct fast blue from the aqueous solution was studied. The key influencing factors and the proper absorption condition were given and under the optimum condition the decolorization rate could be reached at 95%.更多还原
