At present, pollution remains the major problem affecting all the life fields in the world, of course, water pollution was representing a high percentage of an obstacle, one of these contaminants was dyes, and many efforts were done to remove them from water. Adsorption was used as an efficient technique for this purpose. In this study activated charcoal derived from Iraqi date core was utilized as a surface adsorbent for the contaminated dyes, different parameters including contact time. weight of the adsorbent, zero-point charge, and acidity function at various degrees of temperature were studied. The obtained result indicates that the best time was 180 and 30 minutes for Safranin O and Bismarck Brown y respectively while the optimum weight of adsorbent surface 0.05 gram for both dyes, a good percent of dyes removal has been obtained. Also, the thermodynamic adsorption refers that it's spontaneous for Bismarck Brown Y while nonspontaneous for Safranin O with a little energy requirement. However, the investigation of the adsorption isothermal models showed a different behavior for both dyes. So, this type of surface adsorbent could be used for the removal of contaminated dyes from the water as a technique of water purification
