Abstract:

We present herein a digestion method based on high-temperature (260 °C) microwave heating and strong acidic media in order to perform a complete digestion of nonwoven textiles, which can be found in face masks. In particular, this protocol allows the digestion of PET-, PTFE-, polyamide- and elastane-containing textiles resulting in a complete release of metallic contents in order to analyze their elemental contents by ICP techniques.
