磁性生物活性炭的制备及其在印染废水脱色中的应用

Preparation of magnetic biological activated carbon and its application in decolorization of printing and dyeing

通过化学共沉淀法制备磁性生物活性炭,并采用X射线衍射(XRD)和透射电镜(TEM)对其形貌结构进行表征分析,然后应用于亚甲基蓝溶液脱色的处理中。结果表明,当亚甲基蓝溶液初始浓度为10 mg/L,p H值为9,吸附时间为60 min,磁性生物活性炭的投加量为0. 05 g/L时,对亚甲基蓝溶液的脱色率达到99%。

The magnetic activated carbon was prepared by chemical co-precipitation in the treatment of decolorization of methylene blue solution,which was characterized by X-Ray Diffraction（ XRD） and Transmission Electron Microscopy（ TEM）. The results showed that when the initial concentration of methylene blue solution was 10 mg/L,the pH value was 9,the adsorption time was 60 min,and the dosage of magnetic biological activated carbon was 0. 05 g/L,the decolorization rate of methylene blue solution reached 99%.
