Abstract A capillary zone electrophoresis (CZE) method was developed to separate and determine chlorinated phenols in water and soil samples. A mixture of 16 chlorinated phenols was resolved in 25 min by using a 77 cm (70 cm to detector) × 75 μm fused silica capillary with 0.015M tetraborate/0.045M phosphate (pH 7.3) buffer at 22 kV. Calibration linearities for water samples in the low parts-permillion range were good (correlation coefficient > 0.99) for all solutes except p-chlorophenol. Average precision was 17% relative standard deviation. Typical detection limits were in the 200 μg/L range. Recoveries of chlorinated phenols from synthetic soil samples with methanol were quantitative.
