摘要

以溶剂热法制备了一种多壁碳纳米管-四氧化三铁(MWCNT-Fe3O4)复合材料,并以此作为分散电极,制备了三维电催化氧化电解池,对蒽醌染料分散蓝2BLN进行脱色。通过透射电镜(TEM)、X射线衍射仪(XRD)、傅里叶红外(FT-IR)对MWCNT-Fe3O4复合材料进行相组成、形貌及结构分析表征;以分散蓝2BLN的脱色率作为评定标准设计正交试验,通过极差和方差分析探讨电压、电解盐浓度和催化剂用量对脱色率的影响规律;探讨分别以MWCNT-Fe3O4、MWCNT和Fe3O4作为附加电极时,对染料脱色率的影响。结果表明:各因素对脱色率的影响程度由大到小依次为电压、电解盐浓度和催化剂用量;以MWCNT-Fe3O4作为附加电极,在电压为17V,电解盐浓度为1mol/L,催化剂用量为75mg/L的条件下,对分散蓝2BLN脱色,3h后脱色率可达到98.79%。

Abstract

A multi walled carbon nanotube ferric oxide (MWCNT-Fe3O4) composite was prepared by solvothermal method.The 3D electrocatalytic oxidation cell was prepared by using MWCNT-Fe3O4 as dispersion electrode.The decolorization of anthraquinone dye Disperse Blue 2BLN was carried out.The phase composition,morphology and structure of MWCNT-Fe3O4 were characterized by transmission electron microscope (TEM),X-ray diffractometer (XRD) and Fourier infrared (FT-IR).The decolorization rate of Disperse Blue 2BLN was used as the evaluation standard design in the orthogonal experiment,the effects of voltage,electrolytic salt concentration and catalyst dosage on the decolorization rate were discussed through range and variance analysis.The effect on the decolorization rate of the dye was studied when MWCNT-Fe3O4,MWCNT and Fe3O4 used as additional electrodes,respectively.The experimental results shown that the degree of influence of various factors on the decolorization rate was in order of voltage,electrolytic salt concentration and catalyst dosage.MWCNT-Fe3O4 was used as an additional electrode at a voltage of 17V,electrolytic salt concentration of 1mol/L,and catalyst dosage under the condition of 75mg/L,the discoloration of Disperse Blue 2BLN can reach 98.79% after 3h.
