The objective of this work is to study the sorption behavior of Linear Alkylbenzene sulfonate (LAS) onto El-Mex Bay sediments. The Bay is a part of Alexandria coast on the Mediterranean Sea located in Northern Egypt. The study showed homogenous distributions of LAS homologues in El-Mex Bay sediments. The range of the LAS concentration in sediments was between 0.370 and 0.540 μgg-1 dry solids. High total LAS concentrations in the bay sediments coincide with small amounts of DO (0.5-1.9 mgl-1) and low Eh values. The LAS homologues were usually detected between 10 and 13 carbon atoms, with C11- and C12-LAS; they are the most adsorbed on the bay sediments. Sorption experiments on the Bay sediments were performed with different organic matter content (ranged from 0.9 to1.16%) and were applied at different pH values (3.8, 8.5 and 12). The sorption behavior of LAS on El-Mex Bay sediments is satisfactory described by the Freundlich and Stern-Graham isotherm equations. Based on the data presented in this work, the following conclusion was drawn: Sorption distribution coefficients were significantly increased with the increasing the organic matter content due to the hydrophobic interaction between the alkyl chain and organic carbon content of the sediment. LAS sorption on sediments was strongly affected by pH and decreased with increasing pH value for each sediment sample which can be attributed either to electrostatic interactions or to specific chemical interactions.
