Unfortunately, pollution represents the major dangerous silent weapon in the world now a day, especially after technological development. Water contamination takes a high percentage of the distributed pollutant over the earth, and so many efforts have been made to remove such contamination. Type of dyes also was used in this study to calculation thermodynamic process .,Dyes which is colored materials that can bind in some way to the materials and give them bright colors. These dyes are considered pollutants of water and have toxic effects on humans. Studying the adsorption of fast-green and malachite-green dyes from their aqueous solutions on the surface of charcoal derivative from the kernels of Iraqi dates activated with citric acid as an economic method. Several parameters were studied to investigate the most optimum condition that improves the adsorption process. The adsorption study carried out on the Activated Charcoal derivative from Iraqi Date Cores., The results obtained after conducting several effects showed the contact time (90 minutes for fast green, and malachite green 30 minutes), the acidity function, as well as the different temperatures (290 to 320 K) .
