✦ Synopsis

The influence of the surfactant nature and concentration in the mobile phase on the separation selectivity of fifteen benzene and naphthalene derivatives in Micellar Liquid Chromatography has been determined by using an octadecylsilica column. Sodium dodecylsulphate (SDS), hexadecyltrimetylammonium bromide (CTAB) and polioxietilen [23] dodecanol have been used at concentrations ranged from 0.02 M to 0.1 M. A multiple linear regression program has allowed to find an expression for the selectivity as a function of the two parameters studied (surfactant nature and concentration).
