摘要

A reversed phase-high performance liquid chromatographic (RP-HPLC) method is applied for determining octanol-water partition coefficient (Kow) of DDTs. For this purpose, a semi-experimental equation is established by plotting a set of shake-flask Kow values against the corresponding corrected retention times (CRT) of 10 benzene homologues, which are chosen as model compounds in this study. The physicochemical data Kow for 3 DDTs (p,p'-DDD, o,p'-DDT, and p,p'-DDE) and Dicofol were calculated by using this equation. In addition, the measured log Kow values for verification compounds (p,p'-DDT and HCB) determined by RP-HPLC method and software-computed method were compared against shake-flask data respectively, and the RP-HPLC values were found to give better consistency with shake-flask results.
