  1. Samples of South China seawater (10 mL) were spiked with phenols at 10.0 ng/mL and extracted
  2. aCA was calculated as the concentration of the analyte extracted
  3. bThe enrichment factor (EF) of the analytes was calculated as the ratio of the analyte concentration after extraction to that in the original sample
