摘　　要：利用零价铁的还原性质,将难生物降解的有机物硝基苯先还原生成亚硝基苯,然后再进一步还原成可生物降解的苯胺。实验得出在室温和酸性条件下,控制反应体系的pH值为6.0～7.5,Eh值在-172～-266 mV之间,可使硝基苯的还原率达到97.4%。By the deoxidization of zero-valent iron, nitrobenzene, an organic compound deoxidized to nitrosobenzene, and further to aniline, which is easily biodegraded. hard to be biodegraded, can be Experiment shows that under laboratorial temperature and acidic conditions, the deoxidization rate of nitrobenzene could reach 97.4% when pH is 6.0--7.5, and Eh is -172--266 mV.
