This paper introduced preparing PP/PE compound by heating mixing & injection molding, as well as qualitative and quantitative detection by Fourier Transform Infrared Spectroscopy (FTIR). The FTIR of PE was analyzed and 719cm-1 was determined as the characteristic absorption peak for PE. The influence of PE content on infrared spectrogram and standard curve was studied, showing that the content of PE had a good linear relationship with the absorption strength of its characteristic peak. Their correlation coefficient was 0.9992 with a recovery coefficient of 96.50% at least. Finally, the research method was successfully applied to the determination of PE content in recycled PP, which brought profound significance in the analysis of recycled PP/PE compound in the future.
