Abstract:
With increasing global consumption of plastics and motivation towards plastic recycling for sustainability, simple yet accurate analysis of inorganic content in polymers (virgin as well as recycled) is crucial. X-ray Fluorescence (XRF) is an elemental analysis technique widely used in industry due to its fast and easy sample preparation approach and non-destructive multi-elemental analytical capability. This technique is heavily used in industrial labs to monitor and improve production processes, control final product quality, and ensure compliance with regulatory standards. Wavelength-dispersive XRF and Inductively Coupled Plasma Optical Emission spectroscopy (ICP-OES) are established analytical techniques for accurate determination of metals in polymers. However, with the increased need of analyzing recycled materials, simpler and on-field implementable tools are now desired for this type of quantitation. In this regard, Energy dispersive (ED) XRF technology available in the form of compact benchtop units and handheld/portable (P) XRF units are ideal. This work will compare the analysis capabilities of a suite of analytical techniques ranging from the highly sensitive wavelength dispersive (WD) XRF to the handheld XRF units. Polymer standards available from XRF standard manufacturers will be used for this evaluation. This study will be crucial in understanding the limit of detection, sensitivity, advantages, and limitations of different analytical tools and help determine the right technology for different applications.
