The sorption-desorption behavior of Linear Alkylbenzene Sulphonate (LA
S) on marine sediments from three different areas of the Thermaikos Gu
lf in Northern Greece was studied. The sorption of LAS on sediments is
satisfactorily described by the Freundlich Equation. Positive correla
tion exists between the sorption of LAS and the organic matter. Unlike
sorption (1/n = 1), the desorption isotherms were linear (1/n = 1) fo
r all three types of sediments. (C) 1998 Elsevier Science Ltd.
