| Abstract | BIOSIS COPYRIGHT: BIOL ABS. Small exothermic or even endothermic heats of sorption for organic compounds in soft organic matter (SOM) have been traditionally considered evidence for a partitioning mechanism into the bulk of SOM. This derives from considerations of solute transfer enthalpy (DELTAHtr) from aqueous solution to organic solvent and partial molar enthalpies of solution in organic solvent (DELTAHsols) and aqueous (-DELTAHsolw) phases, where DELTAHtr = DELTAHsols - DELTAHsolw. The dissolution of many solutes in organic solvents is accompanied by positive solution enthalpies and conforms to the condition DELTAHtr -DELTAHsolw. It was suggested by analogy of SOM to organic solvents, that solute sorption enthalpies (DELTAHi) in SOM that conform to the analogous condition (i.e., DELTAHi -deltaHsolw) are consistent with partitioning into SOM. Systems that do not conform to this condition (i.e., DELTAHi -DELTAHsolw) were considered to be consistent with adsorption. The purpose of |
