For a student to perform a quantitative analysis of the chemical treatment of PET (Polyethylene Terephthalate), they can utilize several analytical methods to measure the extent of degradation and identify the resulting compounds.Combined Absorption/1H NMR Method: A combined approach using bulk absorption measurements and 1H NMR analysis can provide both qualitative and quantitative data on PET degradation products.

For a student to perform a quantitative analysis of the chemical treatment of PET (Polyethylene Terephthalate), they can utilize several analytical methods to measure the extent of degradation and identify the resulting compounds. Here are two methods that are particularly useful:
Quantitative 1H-NMR Spectroscopy:
This method allows for the identification and quantification of PET degradation products in environmental samples. It’s especially useful for evaluating the effects of different matrices on the identification and quantification of PET1.
Combined Absorption/1H NMR Method:
A combined approach using bulk absorption measurements and 1H NMR analysis can provide both qualitative and quantitative data on PET degradation products. This method has been optimized for different solvents, pH values, and drying processes, offering sensitivity limits suitable for detecting PET degradation products2.
These techniques can help the student accurately measure the efficiency of chemical treatments applied to PET and contribute to the development of effective recycling strategies.
