TRANSPORT CHARACTERISTICS OF GAS PHASE OZONE IN UNSATURATED POROUS MEDIA FOR IN-SITU CHEMICAL OXIDATION

Description of three porous media (glass beads, sands and soils) into pyrex glass columns used for experiments. Schematic of soil column experiment shows the injection of gaseous ozone. Transport and decomposition characteristics of ozone and breakthrough curves (BTCs) in various soils are done. Effects of water content on ozone transport ,flow rate, soil organic matter (SOM) and metal oxides (MOs) are doiscussed. Ozone transport and phenanthrene removal are commented. Residual concentrations of eight diesel-range organics (DROs) in soil column are analysed.
