Abstract
A reverse-phase high pressure liquid chromatography/mass spectrometry (HPLC/MS) method was developed for estimating n-octanol/water partition coefficients (K sub ow) of anthropogenic molecules in complex chemical mixtures (e.g., complex effluents and solid waste leachates). The average error for an estimated log K sub ow was ca.0.5 and this error was similar for both aliphatic and aromatic compounds. The minimum level of detection using the total ion current profile generally decreased with increasing molecular weight between 100 and 600 daltons. Results obtained demonstrate that the HPLC/MS method is a viable technique for estimating log K sub ow's of anthropogenic chemicals in complex environmental samples.
