This team integrates the experts in three fields (chemical engineering, environmental engineering and mechanical engineering) to investigate the feasibility of SFE in dioxin contaminated soil in An-shun site. The aims of this study are to investigate the effect of temperature, pressure, extraction time, water content, soil type and co-solvent on SFE efficiency. The results of this study can be in practically applied in scale up design and compared with other technologies in economically. By the way, this study will be an in the lead and novel technology in the world.
