| 摘 要： | 采用原位水热法制备纳米NiO/沙柳活性炭复合材料(NiO/SAC),通过扫描电镜(SEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)等仪器对其结构和形貌进行表征,并研究NiO/SAC对废水中苯酚的去除能力,考察催化剂用量、苯酚溶液初始浓度、pH等因素对苯酚去除率的影响。结果表明:花状的氧化镍均匀地分散于活性炭的表面,质量分数约为2%,在NiO/SAC复合材料吸附与催化降解双重作用下,在催化剂投加量为5 g/L、苯酚溶液pH为6时,苯酚去除率可达95%以上; NiO/SAC在pH 3～11宽范围内,对苯酚的去除率均在80%以上,是理想的工业苯酚废水处理材料。

| Abstract: | Nano-NiO/Salix activated carbon composites (NiO/SAC) were prepared by in-situ hydrothermal method. The structure and morphology of the composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and the catalytic degradation of phenol in waste water by NiO/SAC was studied. The effects of pH value, catalyst dosage and initial phenol concentrations on the degradation efficiency of phenol were investigated. The results show that petal-like nickel oxide was uniformly loaded on the surface of activated carbon and the capacity of NiO was 2%. Under the dual action of adsorption and catalytic degradation of NiO/SAC composite, the phenol removal rate could reach over 95% when the catalyst dosage was 5 g/L and the pH of phenol solution was 6. NiO/SAC could remove phenol more than 80% in the pH range of 3-11, and it is an ideal material for the treatment of industrial phenol waste water. |
