A distributed reactivity model for sorption by soils and sediments. 11. Slow concentration-dependent sorption rates
Article Abstract:
The Dual Reactive Domain Model proved to be applicable in the interpretation and description of sorption rate behavior. Experimental investigation using seven EPA reference soils and sediments and six shale and kerogen samples revealed that attainment of apparent sorption equilibrium by the phenathrene probe relies heavily on the aqueous phase-solute concentration and the type of soil organic matter (SOM) associated with a particular sorbent. The dependency can be attributed to differences in solute diffusion behavior within chemically reduced and structurally condensed SOM domains and in highly amorphous SOM domains.

Chemical characterization of a chelator-treated soil humate by solution-state multinuclear two-dimensional NMR with FTIR and pyrolysis-GCMS
Article Abstract:
Research focusing on the chemical characterization of a chelator-treated soil humate by solution-state multinuclear two-dimensional NMR with FTIR and pyrolysis-GCMS. The research indicated that peptidic moieties might be more readily accessible to aqueous contaminants than aromatic groups.
