Abstract
Abstract The sorption behavior of 2-naphthol on marine sediments treated by different methods was systematically investigated. Through experiments and analyses, some important conclusions were obtained. About 10 h were required for sorption equilibrium of 2-naphthol on marine sediments. The sorption behavior of 2-naphthol on marine sediments accorded well with the linear sorption isotherm. The sorption occurred principally via partition function of organic carbon of sediments. The sorption of 2-naphthol was controlled not only by the organic carbon content of marine sediment, but also by the external factors such as salinity of water and temperature. As ionic strength (salinity) increased, both concentration and ionization of 2-naphthol in solution would decrease. Simultaneously, release of the solvable part of organic carbon into water solution would decrease with increasing salinity. As a consequence, partition coefficients ( K d ) increased with the increase of salinity of seawater. Contrary to the influence of salinity, partition coefficients decreased with the increase of temperature.
