Abstract: The change of the consistency of ethylene in the process of photo-catalyst titanium dioxide by gas chromatographicwas studied in this paper. Standard curve was used in the analyzing the change of the consistency of C2H4. The coefficient of recoverywas 95.1%, Linear correlation coefficient of the standard curve 0.9994, standard deviation 0.6% and aberrance coefficient 2.2%.The method was utilizable in analyzing ethylene consistency change in the process reaction of photo -catalyst of titaniumdioxide. It was accurate and useful.
