These processes complicate their transport in porous medium and contribute to pores colmatage in soil. This work deals with the description of suspension transport of nZVI TODA laboratory stabilized by silica and with simulation of PCE destruction in modeled saturated soil (grain size of 0,25 to 2,5 mm). Transport experiments were performed with 6 suspensions of different Fe concentrations and volume ratios silica / TODA. Degradation experiment was based on the system with the flow of PCE aqueous solution with concentration of 104 mg/l through the soil, previously enriched nZVI. For description of transport and degradation experiments was used mathematic program MATLAB. For evaluation of the Fe nanoparticles suspension flow and its capture in the pores of the soil were in this work defined these variables: the capture coefficient KD and the colmatage coe"@en .
