A method to estimate the octanol-air partition coefficient of semivolatile organic compounds.

摘要: A multicolumn method for the estimation of octanol−air partition coefficient (KOA) semivolatile compounds is described. The based on retention time a compound gas chromatographic columns different selectivity and polarity. Log KOA values polychlorinated biphenyls (PCB) were estimated with novel method. results in excellent agreement previously published data using generator column Therefore, we used our to estimate more than 100 PCB congeners.
