| 摘 要： | 采用Tween-20作为包覆材料对纳米零价铁(n ZVI)进行改性(T-n ZVI),并利用T-n ZVI活化过硫酸盐(PS)降解柴油,同时与未改性纳米零价铁活化过硫酸盐体系(n ZVI/PS)进行对比.结果显示,在n ZVI/PS体系中,柴油降解率随着n ZVI及PS用量的增加而增加.在T-n ZVI/PS体系中,反应90 d后,柴油最大降解率为78%.与n ZVI/PS体系相比,T-n ZVI/PS体系所有组别的柴油降解率均有所提升,但提升幅度不大.同时对T-n ZVI活化PS的机理进行了推测. |

| Abstract: | In this study, Tween20 was chosen to coat nano zero valent iron (T-nZVI). The feasibility of remediating diesel-contaminated soil using persulfate(PS) activated by T-nZVI and nZVI was then investigated. It was observed that larger amount of T-nZVI favored PS decomposition and diesel degradation. The maximum degradation efficiency of diesel was 78% within 90 days in the T-nZVI system. Compared with the nZVI system, the degradation efficiency of diesel was slightly higher in the T-nZVI system. Possible mechanism of persulfate activation by T-nZVI was inferred based on the analysis data. |
