The 70 um polypropylene membrane with 64-80 %porosity could be prepared by using supercritical CO2 instead of organic solvents. The average pore size of the membrane was about 2~5 umwith 10~30 polypropylene wt%. The porosity decreased with an increasing polypropylene concentration and breaking point with 10, 20, and 30 polypropylene wt% was 0.17, 0.24, and 0.46 Kgf/mm2, respectively. A 94% and 99% of initial camphene concentration was extracted in 5 min and 10 min, respectively, and kept constant at 99% over 10 min. The optimum conditions to extract camphene effectively were 45˚C and 150 bar.
