Title: The Influence of Ionic Strength on the Partition Coefficient of Polycyclic Aromatic Hydrocarbons and Dissolved Organic Matter
Author: Hui-Ling Wang
Abstract: ABSTRACTHydrophobic organic pollutants (HOPs) are in general characterized by high toxicity, long environmental half-life and high bio-accumulation factors. Due to their hydrophobicity, HOPs tend to sorb onto particulates in natural aquatic environment and their degradation pathways and rates are altered with the change of the reaction media and the settlement of these particles. The influence of the dissolved organic matters (DOMs), termed as the third phase, on the sorption partition coefficient is observed because of their interactions with HOPs. This binding (between DOM and HOP) increases apparent solubility and mobility of the HOP and the sorption coefficient of HOP in (more...)
