AB  - n-Octanol/water partition coefficients (logKow) for persistent organic pollutants 
      (POPs) including polycyclic aromatic hydrocarbons (PAHs), polychlorinated 
      dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and 
      decabromodiphenylethane (DBDPE) have been determined by a modified method of 
      reversed-phase high performance liquid chromatography (RP-HPLC). A dual-point 
      retention time correction (DP-RTC) was used to rectify chromatographic retention 
      time (tR) shift resulted from stationary phase aging and so on. Based on this 
      correction, the relationship model between logKow and logk(w), the logarithm of 
      the retention factor extrapolated to pure water, was trained by a set of model 
      compounds (a total of 37) with reliable experimental logKow as training set, 
      including benzene homologues, PAHs and PCDD/Fs-related compounds. A linear 
      regression equation of logKow = (1.18 +/- 0.02) logk(w) + (0.36 +/- 0.11) was 
      established with correlation coefficient (R2) of 0.985, cross-validated 
      correlation coefficient (R2cv) of 0.983 and standard deviation (SD) of 0.16. This 
      quantitative structure retention relationship (QSRR) model was further validated 
      using four verification compounds, biphenyl, fluorene, PCDD 1 and PCDF 114, with 
      reliable experimental logKow val- ues. The RP-HPLC-determined Kow values showed 
      good consistency with shake-flask (SFM) or slow-stirring (SSM) results, 
      especially for highly hydrophobic compounds. Then, the logKow values for 29 POPs 
      of wide interest were evaluated by the improved RP-HPLC method for the first 
      time. The DP-RTC-HPLC method is recommended for the determination of the logKow 
      values of POPs with strong hydrophobicity.
