This work includes the study of the ability of pomegranate peel as adsorbent for two kinds of pesticides (Lambda cyhalothrin and Diazinon) from their aqueous solutions. The equilibrium contact time for the samples was determined. The effect of some factors on the adsorption process which was represented by the effect of acidity function was also studied. It was found that the best adsorption is at pH=2. The effects of the different temperatures within the range (313, 323, and 333K) were studied. The amount of adsorption for the pesticides is decreased with the increase of temperature; this indicates that the adsorption process is exothermic. Finally the study of the adsorption isotherms takes the (S-shape) according to Gile's classification for all the cases from (S2, S4) type which is following the freundlich equation for the adsorption.
