Table I.
Declared particle size | 14 nm | Degussa-Hüls |
Geometric mean size | 65 nm (carbon spheres) | (Saber et al. 2005) |
Morphology | Individual carbon black spheres mainly occurred in open-structured long chain aggregates and fewer large dense aggregates | (Saber et al. 2011) |
Particle size distribution | The aggregates cover a wide size-range from <100 nm to 20–30 mm; the typical aggregate size is approximately 200 nm | (Saber et al. 2011) |
Surface area | 295–338 m2/g | (Saber et al. 2005) (Jacobsen et al. 2008b) |
Pycnometric particle density | 2.1 g/cm3 | (Saber et al. 2005) |
Chemical composition | 99% C, 0.8% N and 0.01% H2 | (Jacobsen et al. 2008b) |
The total PAH content (Carbon black extract – Soxhlet) | 0.0742 mg/g | (Jacobsen et al. 2007) |
The total PAH content (DEP extract – NIST SRM 1650) | 216 mg/g | (Jacobsen et al. 2008a) |
PAH, polycyclic aromatic hydrocarbon (data included for comparison); DEP, diesel extract particles.
