Generally, contaminations on aluminum surface are hydrocarbons, but they are not clarified yet. So, we applied supercritical fluids (SCF) carbondioxide (CO2) treatment on aluminum where triglyceride was deposited. Contamination removing rate was evaluated with FT-IR.<BR>(1) The peaks of triglyceride were -CH3 and -CH2- at 2920 cm-1 and 2850 cm-1, respectively.<BR>(2) Obtained standard lines for evalution are proportional to a square root of contamination of triglyceride in the range from 1% to 30% density. The precision of this standard lines is ±1213%.<BR>(3) Contamination removing rate is in the range of 6798%.Therefore, SCF CO2 is effective to remove triglyceride on the aluminum surface.
