摘要:
磁控溅射、真空蒸镀和真空抽滤三种方法均可制备碳纳米管复合膜。运用扫描电镜 (SEM)、X射线光电子能谱 (XPS)和X射线衍射 (XRD)对不同复合膜的形貌和表面化学性质进行表征,确定复合膜的结构对其除As效率的影响。通过实验探究三种方法制备的不同复合膜对As(III)的去除效率以及不同碳纳米管和天然有机质对复合膜除As效率的影响。结果表明,磁控溅射镀铜的MWCNT-OH和MWCNT-COOH复合膜以及真空抽滤制备的MWCNT-OH复合膜对水中As(III)的去除效率最高,均能达到90%左右,但水中天然有机质的存在会抑制磁控溅射镀铜膜对As(III)的去除。
Abstract:
Magnetron sputtering, vacuum evaporation and vacuum filtration are three methods to prepare carbon nanotube composite membranes. To investigate the effects of composite membranes’ structure on As(III) removal, morphologies and surface chemical properties of different composite membranes were determined by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The impacts of different carbon nanotubes as well as the natural organic matter (NOM) on As(III) removal were also conducted. The results showed that MWCNT-OH and MWCNT-COOH composite membranes modified with nano-copper by magnetron sputtering and the Cu-based membrane fabricated by vacuum filtration had the highest removal efficiencies of As(III) in water, which could be up to 90%. However, the presence of natural organic matter in water inhibited the As(III) removal by these two nanocompoaite membranes.
