bromide (CPB) and cetyltrimethylammonium bromide (CTAB). The retention properties have been studied of these two kinds mesoporous
silicas towards environmental pollutants (mono-, di-, tri-chloroacetic acid, toluene, naphthalene and methyl orange). LC and suppressed
ion chromatography have been used to evaluate the retaining amount of analytes on the mesoporous silica materials. The effect of the composition
(presence and absence of surfactants, different kinds of surfactants) on the sorption performance has been considered. As-prepared
materials show excellent retention performance toward chloroacetic acids, toluene, naphthalene and methyl orange. The materials without
surfactants does not show, if any, affinity for ionic and non-ionic analyte详细>
