Up to now, water pollution is still one of the important issues and challenges worldwide,due to its environmental, economic and human life impacts. It is also remains a challenge toenvironment scientists and technologists. Nowadays, the textile dyeing industry is consideredone of the largest water consuming industries and produces large volumes of colored wastewaterin its dyeing and finishing process. In this study, date palm tree leaflets (DPL) hasbeen selected as a natural renewable source for the production of a new activated carbon(AC) utilized for the removal of crystal violet (CV) from water-dye system using a batchmode technique. The experiments studies were carried out at different initial dye concentration,contact time, adsorbent dose, and pH. The sorption exhibited high efficiency for CVadsorption and the equilibrium state could be achieved in 30 minutes for the different CVinitial concentrations. CV removal was proved to increase with the increase in ACDL dose,pH, and contact time. Agitation rate and total volume of the reaction mixture were kept at200 rpm and 20 mL respectively. The applicability of Langmuir and Freundlich isothermequations was investigated and it was found that experimental data fitted very well to bothFreundlich and Langmuir models. The maximum adsorption capacity (qm) was found to be36.63 mg/g.
