Sorption behavior of nonylphenol on marine sediments: Effect of temperature, medium, sediment organic carbon and surfactant

► NP sorption kinetics accorded with non-linear Ho-McKay pseudo-second-order model. ► Kd values showed positive correlation with sediment OC contents. ► Medium salinity showed positive correlation with Kd and negative with DOC. ► CTAB enhanced NP sorption amount the most while SDBS enhanced the lest. ► NP sorption was an exothermic physical and spontaneous entropy-decreasing reaction.
