The present work describes synthesis of new type of activated carbon (AC) from Iraqi berhy date palm seeds (IPDPS). This type of AC was synthesized using chemical activation method with using ZnCl2 as a chemical activator. The activation process was performed at four different temperatures, 400, 500, 600, and 700 ºC. The synthesized AC was investigated using scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). Different physical properties were undertaken such as ash content, adsorption uptake capacity, humidity, point zero charges of the AC were calculated. The activity of this material was investigated via following removal of reactive yellow dye 145 (RYD145) from simulated industrial textile wastewaters. Removal of this dye in this study was conducted by applying different reaction conditions. These conditions were the amount of the used AC, effect of pH on dye removal a, effect of temperature, and duration of time on the adsorption process. Adsorption isotherm for dye adsorption was investigated and from the obtained results it was follows Freundlich model. The activity of the synthesized AC on dye removal was compared with the non- activated carbon (NAC) that is synthesized from same date palm seeds (IPDPS. The obtained results showed that, the activity of dye removal was effected by activation temperatures of as well as the AC was more efficient in dye removal in comparison with NAC under the same conditions. Also the activity of dye removal was increased with increasing of activation temperatures as follows: AC600 > AC500>AC400>AC700.
