AbstractLaboratory experiments were carried out to investigate the adsorption behaviour of dibutyl phthalate (DBP) on marine sediments collected from five different sites in Victoria Harbour, Hong Kong. DBP adsorption can be well described by the Langmuir isotherm. The maximum DBP adsorption capacity (Qmax) of the marine sediments ranges from 53 to 79 mg g-1, which has a positive correlation with their organic content. Around 90% of the organic can be removed from the sediments with treatment by H2O2 oxidation, and the Qmax then decreases to a range between 13 and 22 mg g-1. The black carbon content of the sediments has a much greater DBP adsorption capacity than does the natural organic matter of the sediments. The amount of DBP adsorbed on the sediments increases as the salinity of the marine water increases. © 2008 Elsevier Ltd. All rights reserved.
