中文摘要:
      利用原位聚合法制备聚苯胺(PANI)改性活性炭(AC)粒子电极,采用金相显微镜、X-射线衍射仪(XRD) 和红外衍射光谱(FTIR)对该粒子电极的形貌、晶体结构和组成进行分析,并将其应用于直接耐晒翠蓝GB (FBL)的光电催化降解实验; 考察PANI复合量、粒子电极用量、电流密度、pH和初始浓度等因素对直接耐晒翠蓝GB降解的影响,并研究了FBL在不同催化条件下的降解。结果表明: 光催化和电催化产生协同作用; 在电解质Na2SO4溶液浓度为 0.03 mol?L-1,粒子电极投加量为 9 g?L-1,电流密度为8 mA?cm-2,pH为3,浓度为20 mg?L-1的FBL溶液的去除率达到 95.47%。
英文摘要:
      Polyaniline (PANI) modified activated carbon (AC) particle electrode was prepared by in-situ polymerization method. The morphology and crystal structure of the particle electrode were studied by metalloscope, X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). And the composition was analyzed and applied to the photocatalytic degradation experiment of FBL; the factors such as compound amount, particle electrode dosage, current density, pH and initial concentration were examined for the degradation of FBL influences and studies on photocatalytic degradation kinetics of FBL. The results show that photocatalysis and electrocatalysis produce a synergistic effect; when the concentration of electrolyte Na2SO4 solution is 0.03mol?L-1, the particle electrode dosage is 9 g?L-1, the current density is 8 mA?cm-2, and the pH is 3, the removal rate of FBL with a concentration of 20 mg?L-1 reached 95.47%.
