The sorption behavior of DDT onto sediment in the presence of surfactant cetyltrimethylammonium bromide

► The sorption behavior of a complex system consists of DDT and CTAB onto marine sediment was studied. ► Batch experiments were carried out to investigate the kinetics and thermodynamics. ► The presence of CTAB could remarkably accelerate and enhance the sorption of DDT. ► The sorption of DDT had relatively more negative ΔG0 and ΔH0 in the presence of CTAB.
