Quantitative Analysis of Recycled Plastics Using FTIR - Mixing Ratio Calculation Method -

This study examined simple methods for quantitative analysis of PE, PP, PS, and PET in recycled plastics using FTIR. The results suggest that for samples in pellet form, the mixing ratio calculation method described in this article may be able to obtain quantitation values that indicate a correlation with NMR values. Since the accuracy of the calibration curves greatly affects the results of quantitative analysis, further examination is necessary in selecting a typical peak that best represents each component, calculating the mixing ratio, and determining quantitation conditions.
