A　simple　analysis　of　chlorophenols　(2-chlorophenol,　2,4-dichlorophenol,　2,4,6-trichlorophenol,　and　pentachlorophenol)　and　phenol　was　accomplished　by　coupling　a　pressurized　CEC　with　amperometric　detection　(AD).　Efficient　and　reproducible　separation　of　these　compounds　was　achieved　within　9　min　on　a　capillary　monolithic　stationary　phase　bonded　with　octadecyl　ligands　and　sulfonate　groups,　where　the　selectivity　and　the　retention　of　analytes　can　be　functionally　controlled　by　optimizing　experimental　variables,　including　organic　modifier　content,　mobile　phase　pH,　ionic　strength,　working　electrode　potential,　separation　voltage,　and　supplementary　pressure.　A　mixed-mode　retention　mechanism　consisting　of　reverse-phase　chromatographic　partition,　electrostatic　repulsion,　and　electrophoresis　is　considered　to　play　roles　in　the　separation.　The　use　of　ACN-based　media　seems　effectual　in　preventing　the　unfavorable　irreversible　adsorption　on　both　wall　and　electrode,　and　offer　higher　sensitivity　and　less　electrode　fouling　in　AD　of　phenols.　The　LODs　were　in　the　range　from　0.02　to　0.2　g/mL　with　a　wide　linear　dynamic　range　of　5000-fold,　while　the　peak　area　precision　ranged　from　3.2　to　7.5%.　The　feasibility　of　using　this　method　in　real　analysis　was　evaluated　by　recovery　estimates　and　comparative　experiment　on　spiked　tap　water　samples.　Good　recoveries　of　80-110%　were　achieved.　Additionally,　a　paired　t-test　was　used　to　correlate　the　two　methods.
