Mass transfer and bioavailability of PAH compounds in coal tar NAPL-slurry systems. 1. model development
Article Abstract:
A multi-step mass transport-degradation model could be a useful tool in determining the equilibrium partitioning of polynuclear aromatic hydrocarbon (PAH) compound at the non-aqueous-phase liquid (NAPL)-water interface. The initial process could then be followed by three sequential kinetic processes occurring in the aqueous phase. The overall rate of biotransformation of organic compounds from NAPLs appears to be influenced by NAPL-water equilibrium processes .

Organic phase resistance to dissolution of polycyclic aromatic hydrocarbon compounds
Article Abstract:
The dissolution of phenanthrene, pyrene, and naphthalene from viscous organic phases into water was studied in continuous-flow systems for time periods ranging from a few months to more than a year. The governance of mass transfer was shown to vary from water phase control to nonacqueous phase control when selecting nonaqueous phases ranging from low viscosity to semisolid, i.e., from a light lubricating oil to paraffin.
