Activated Carbon characterized by special importance for it’s large use in industry field and pollution struggle it has been prepared from different sources and ways.                                               <br /> In this study activated carbon was prepared from seed residues of (<em>Urtica dioica) </em>plants after extractions of vegetable to preparation the biodiesel.                        <br />  <br /> The process of activated carbon preparation include the following steps:<br /> 1)      Primary carbonization of theseed residues at (300º±50ºc).                     <br /> 2)      Secondary carbonization of product results from the primary carbonization with exiss amount of sodium hydroxide {(1:2) (seeds residues:NaOH)} at (500±25ºc) for 3 hrs. The product washed with: distillated water treated with 10% HCl, washed with distillated water and ther dried at 110ºc for 24 hrs.<br /> Number of tests concerning the activated carbon were parformed including all types of activated carbon prepared in steps 1and 2, these tests including:                                                                       <br /> Physiochemical tests such as humidity, density, ash content and mechanical  resistance and measurements of iodine number and methylene blue.<br /> The studying results show that carbonization seed residueswith sodium hydroxide in (2)  give the best results of the prepared activated carbon than in (1).
