摘要:
以有机膨润土(CTAB-Bent)为载体,通过FeSO4与NaBH4反应制得有机膨润土负载纳米铁(NZVI/CTAB-Bent),并用X射线衍射(XRD)、比表面积(BET)和透射电子显微镜(TEM)对NZVI/CTAB-Bent的结构和形貌进行了表征。研究了NZVI/CTMAB-Bent对偶氮染料活性艳红X3B的反应性能,考察了pH、染料初始浓度对其去除率的影响,并与相同铁含量的纳米铁(nanoscale zero-valent iron, NZVI)进行了比较。此外,还对NZVI/CTMAB-Bent还原活性艳红X3B的机理进行了初步探讨。结果表明:有机膨润土作载体较好地克服纳米铁易团聚的缺陷;在相同的实验条件下,NZVI/CTAB-Bent对X3B的去除率远高于相同铁含量的NZVI,也明显优于相同含量的有机膨润土和相同铁含量的NZVI对X-3B去除率的加和。此外,NZVI/CTAB-Bent还具有更好的重复使用性。
