| 英文摘要 | Proper disposal of sludge from wastewater treatment plants became a great challenge because of the increasing massive production along with strict environmental specifications, and resource utilization was an attractive alternative solution. In this study, we prepared the dissolved organic substance-based amyloid-fibrils-like functional materials (DOS-AFs) with a long-chain fibrous structure and plentiful active surface groups from both anaerobically digested sludge (ADS) and waste activated sludge (WAS). The optimum pH for DOS fibrosis is observed to be pH 1 and 2. The tiny particle rather than fiber is observed at an elevated pH of 5. DOS-AFs exhibit a good performance toward different heavy metals of Cu, Ni, Zn, Pd, and Ag, and the adsorption capability of WAS-DOS-AFs-1 was 4.9, 3.8, 4.5, 11.5, and 23.2 mu g/mg dry solid, respectively. The 3-D excitation-emission matrix (EEM) spectra results indicated that the proteins and humic substances in DOS-AFs were both strong ligands for heavy metals. The formation of surface complexes was the dominant mechanisms involved in the adsorption; and Fourier transform infrared (FTIR) spectroscopy analysis indicated the amide and ether groups are the main adsorption sites on ADS-DOS-AFs, whereas the amide and hydroxyl groups on WAS-DOS-AFs dominate in the adsorption. DOS-AFs with good adsorption performance are potentially valuable for the removal of heavy metals from wastewater and the recovery of precious metals. |
