“…Seawater Natural seawater was collected from Jiaozhou Bay, China, filtered through 0.45-µm filter membranes, and irradiated with strong ultraviolet light to eliminate the effects of natural dissolved organic matter as far as possible (15). The salinity and pH of the seawater were 33.4‰ and 8.03, respectively, and accorded with those in different areas in the world.…”

“…The black carbon, compared with other components in the OC, was relatively refractory and was not easily oxidized by oxidant [20]. In addition, Yang and Zhang [19] and Tian et al [22] used the same method to treat the sediment samples and measured the OC before and after H 2 O 2 treatment. Their results showed that approximately 83% and 81% of the original OC was removed, respectively [19,22].…”

“…The samples were then filtered, air dried, and ground to pass 40-to 80-mesh sieves. This treatment could completely remove the carbonate of sediment [19] so that the percentage of organic carbon content of sediment on dry weight basis increased accordingly.…”

Their results showed that approximately 83% and 81% of the original OC was removed, respectively [19,22]. This evidence confirms that most OC can be oxidized by this treatment, but the most refractory part of OC (e.g., the black carbon) remains in the marine sediments.…”

In the present study, the sorption behaviors of phenanthrene on marine sediments were investigated. Through the study of the adsorption kinetics and isotherms, the adsorption mechanism of phenanthrene on marine sediments was described. The results showed that the adsorption kinetics of phenanthrene on marine sediments could be described by the second-order kinetic equation. The sorption rate of phenanthrene was very rapid, and the equilibrium time was slightly longer in deionized water than in natural seawater. The adsorption isotherms of phenanthrene on all the sediments could be very well described by Freundlich equations. The adsorption capacity of phenanthrene had a significant positive correlation with the sediment organic carbon content. Some external factors that could affect adsorption behaviors of phenanthrene were also investigated. Results of the present study showed that the adsorption capacity of phenanthrene on the sediment decreased with increasing temperature. Moreover, the adsorption amounts of phenanthrene on the sediment appeared to be lower in natural seawater than in deionized water. Finally, the presence of the surfactant of Tween20 in the system could enhance the adsorption of phenanthrene on the sediment, and the adsorbance was proportional to the concentration of Tween20.

“…1,2 Shirasu may have a significant effect on the behavior of trace elements in this region, since the adsorption of chemical substances in the environment can be closely related to the geological characteristics. Many studies on the adsorption of chemical substances on clay minerals, 3 marine or river sediments, [4][5][6][7][8][9] soil, 10,11 etc. have been conducted.…”
