WebSep 23, 2006 · Abstract. The phenomenological theory of solvent effects partitions the free energy change of a process into contributions from solvent-solvent interactions (the general medium or solvophobic effect), solvent-solute interactions (the solvation effect), and solute-solute interactions (the intersolute or intrasolute effect). WebSometimes the chromatographic literature refers to this as the solvophobic effect. The K + fears the solvent and so spends more time in the resin. The relative retention order based on mobile phase effects would be lithium first and potassium last, as shown in Figure 60, the exact opposite of what was predicted above based on stationary phase effects.
WebDec 1, 2014 · Solvophobic effects strongly influence the thermodynamic properties of solutions and are one of the driving forces of self-assembly processes of supramolecular structures.
