| Popis: | Quantifying carbonaceous nanomaterials (CNMs) has largely been limited to soil, water or biological matrices, but the largest application of CNMs is carbon nanotubes (CNTs) embedded in polymers or plastics. This study introduces a two-step analytical method that matches solvents to dissolve a broad range of polymers, with a subsequent programmed thermal analysis (PTA) quantification technique. Hexafluoroisopropanol (HFIP) and chloroform dissolved the broadest range of polymers containing CNMs. Subsequent PTA could accurately detect and quantify multi-walled (MWCNT) or single-walled (SWCNT) carbon nanotubes at an absolute amount of 0.2 μg (0.2 ppm (m m−1) for a 1 g sample) at a high reproducibility ( |
