摘要

The fundamental chemical interactions governing the retention of 15 solutes in 40 micellar reversed-phae liquid chromatographic systems using sodium dodecyl sulfate(SDS), cetyltrimethylammonium bromide(CTAB), methanol, n-propanol, and n-butanol as mobile phase additives are studied using linear solvation energy relationships(LSERs). The ifluence of solute properties on retention in MLC and the trends in the coefficients as a function of SDS and CTAB concentrations are investigated. The ability of t he LSERs to account for the chemical interactions underlying solute retention is shown. A comparison of predicted and experimental retention factors suggests that LESER formatlism may not completely model the energetics of r etention in MLC, but that the discrepancies, although systematic, are generaly small. Finally, the effects of the addition of 0.035 M SDS to 10% methanol/90% water mobile phases on solute retention are discussed.
