Samenvatting:
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.
