Sorption of benzene and naphthalene on (semi)-arid coastal soil as a function of salinity and temperature by NgueleuS.K.

“…The sorption of naphthalene was not affected by the change in salinity but increased by 18% when the temperature decreased from 35 to 5 �C. A sorption kinetic model was also applied to define the sorption behavior of benzene and naphthalene for the coastal soil collected in Qatar and the best fits were achieved with the Langmuir sorption isotherm.…”
