Technical approach
Subparticle-scale analytic methods:
- mL2MS --- PAH location at 30mm spot
- IR microspectroscopy --- organic environment
- EM and WDX --- elemental composition
- Coal petrography --- coal maceral identification
Particle separation and desorption studies:
- Density and size classification
- PAH desorption kinetics using Tenax
- Thermal programmed desorption-MS
Biological assessments:
- Bioslurry aerobic treatment
- Earthworm uptake
- Particle-scale bioavailability
