Sorption and Desorption Characteristics of Naphthalene and BHT on the Sediment Sampled from Lanzhou Reach of the Yellow River

摘要：

The sorption of naphthalene and BHT on the particulates and sediment in Lanzhou reach of the Yellow river was studied. The results show that the sorption of naphthalene and BHT on the particulates and sediment could reach a dynamic balance adequately within 8h. The sorption curves of naphthalene and BHT on sediment are characterized by S shaped isotherm curve and can be well described by Freundlich equation. There is an obvious hysteresis and extreme residues that could not be desorbed absolutely in the desorption experiment of naphthalene and BHT. At the same time, we studied the effect of different hydrological conditions.
