文摘

The aim was to characterize the ozone reaction with phenanthrene adsorbed in two types of soils. Physicochemical properties of soils affected ozone transfer and degradation of phenanthrene. Soil porosity and pore volume modifies contaminant adsorption and variation of crystal sizes. Ozonation is an attractive method to degrade phenanthrene in soil without (80%) and with OM (70%). The partial identification of intermediates and final accumulated products was developed.
