| Abstract | The octanol/water partition coefficient (K-ow) of alpha-, beta-, gamma- and delta-hexachlorocyclohexane (HCH) was determined at 5, 25 and 45 degrees C using the slow-stirring method followed by solid-phase microextraction (SPME) and gas chromatography. The temperature variation of log K-ow is greater between 5 and 25 degrees C (approximate to -0.006 K-1) than from 25 to 45 degrees C (< -0.001 K-1). A preliminary thermodynamic analysis shows that the HCH transfer from water and octanol is slightly exothermic with a gain of entropy. In this respect, no significant differences have been found between the isomers. |
