Summary of Results

Two samples of fully deuterated polystyrene (d-PS) and polymethylmetacrylate (d-PMMA) have been used to evaluate the feasibility of the approach by applying the same internal, isotope labelled polymer standards to different polymer chemical identification and quantification methods: py-GC/MS-Orbitrap, FTIR, Raman microspectroscopy and GC-MS with pre-analytic derivatization/transformation of polymers. It was shown that confident detection of separate traces of deuterated and native polimer can be achieved by all tested methdos.

Significant effort was put to develpment of methdos for preparartion of microparticles of defined and unifrom size.

The next steps will be assessment and harmonization of size distribution, introduction and recovery of internal standards of d-PS and d-PMMA micro- or nanoparticles into sample matrices and extension to other polymer types.

Based on the already achieved results, further activities are planned within the pending application for project EUROPLAST

Interdisciplinary Cooperation

The project main goal is in the field of environmental analytical chemistry and this first year was dedicated to tests and improvements in analysis. Within the environmental analytical chemistry the project covers all aspects of it and aims at universal solution (deuterium labeled internal standard) for different analytical methdos.

In 2021 a Workshop is planned that will offer the inital results to interdisciplinary community.

Budget in accordance to results

The activities carried out in 2020 and summarized above could not have been carried out without funding from the Fram Centre. As the project is ongoing, finalization of results are expected in 2021 provided continuation of funding.

Could results from the project be subject for any commercial utilization
No
Conclusions

The project is in its first year, yet universality of deuterated polymers is fully confirmed for all targeted methdos: Pyrolysis - GC/MS, Chemical transformation - GC/MS, FTIR spectroscopy, Raman microspectroscopy.
