新生态MnO_2制备及处理孔雀石绿的研究

Study on Preparation of Fresh MnO_2 and Its Performance of Degrading Malachite Green

制备了性能优良的新生态MnO2,并采用IR谱图对其结构进行分析,考察了MnO2对MG的降解效果、重复利用性能等。结果显示:MnO2可以在不加任何辅助条件下直接吸附、氧化降解MG,处理效果优良,重复利用性能好,再生后可恢复较佳的活性,自由沉降速度快,操作简单,经济成本低廉,易分离,具有实际的应用价值和可行性。

Nascent state MnO2 was prepared in laboratory.The structure of the laboratory-obtained samples was characterized by IR spectroscopic analysis and its MG degradation activity and reusability were investigated.The results showed that MG was degradated directly and successfully,and the reusability of MnO2 samples was good.The samples also have the advantages of fast free settling velocity,convenient preparation,low cost and ready separation,providing promising practical application feasibility.
