This study investigated the adsorption potential
of diuron and linuron in selected soil samples collected from agricultural
area of Gaza Strip, Palestine and correlated the adsorption results to the soil properties. The adsorption experiments
are based on the batch equilibrium technique and UV-Spectrophotometer method to
determine the equilibrium concentration of both herbicides. Results of
adsorption experiment showed that linuron and diuron are adsorbed in various
amounts in Gaza soils according to the variation in pH, organic matter and clay content.
Adsorption isotherms of both herbicides were linear in the tested
concentration. Fitting the adsorption data to Freundlich equation showed good
fitting and Freundlich constants were less than one indicating physical
adsorption processes. It is concluded that soil organic matter and pH affect
the adsorption of both herbicides. These results provided a better
understanding of the behavior of diuron and linuron in Gaza soils.
