Abstract: Based on results of simulated experiment, it can determine the main effect factors of nitrobenzene’s transport and fate, as well as effect degree of these factors by analytic method. The study has indicated that the adsorption capability of nitrobenzene transporting in silt medium is better than that in sand medium. The retardation coefficients are 2.22 and 1.74 of silt medium and sand medium respectively. According to first-order reaction, nitrobenzene’s total natural attenuation rates constant are 0.063 5/h and 0.005 9/h respective of silt medium and sand medium. However, biodegradation is the most important factor in the process of nitrobenzene’s migration and transformation, and its effect degree can reach about 50% account for the total natural attenuation capability in either silt medium or sand medium.

Key words: nitrobenzene, aquifer, transport and fate, effect factors
